Usage Precautions

Operating Environment

•

Please use the MDB-100 only when the ambient temperature of the environment into which the MDB-100 is installed is within the following specified temperature limits:

Operation Storage

•

Avoid installation locations that may be subjected to large shocks or vibrations.

•

Avoid installation locations that may be subjected to rapid changes in temperature or humidity.

: -10 ∼ +40°C (+14 ∼ +104°F)

: -25 ∼ +65°C (-13 ∼ +149°F)

Installation

•

Do not touch charged parts of the drive such as the terminal block while the drive’s CHARGE lamp is lit. A charge will still be present in the drive’s internal electrolytic capacitors, and therefore touching these areas may result in an electrical shock. Always turn all drive input power supplies OFF, and wait at least 5 minutes after the CHARGE lamp has gone out before connecting communication cables or motor wiring.

•

Route all communication cables separate from the inverter input/output power wiring.

•

To avoid the possibility of electric shock due to leakage currents, always ground the inverter unit’s E/GND terminal and the motor. To avoid misoperation, do not connect the MDB-100’s SHIELD terminal to either of the above-mentioned grounds or any other power ground.

•

When making connections between the MDB-100 and S7 drives, do not use cables that exceed 5 meters in length.

•

For further drive-specific precaution, safety and installation information, please refer to the appropriate Toshiba documentation supplied with your S7 drive.

Other Precautions

•

The drive’s EEPROM has a life span of 10,000 write cycles. Do not write to the same holding register (other than registers 7A00 ∼ 7A02 and FA00 ∼ FA02 or write-only coils) more than 10,000 times.

•

The MDB-100’s EEPROM has a life span of 100,000 write cycles. Do not write to the same MDB-100 configuration register more than 100,000 times.

•

Do not touch or insert a rod or any other item into the MDB-100’s case while power is applied, as this may lead to electrical shock or device damage.

•

Commission the disposal of the MDB-100 to a specialist.

•

Do not assign the same network address to more than one MDB-100 station in the same network. For a detailed explanation of station addressing, refer to section 8.

•

When the MDB-100 is configured to receive its Modbus RTU / ASCII station address from the drive on Channel A, be sure to reset the MDB-100 if the inverter number parameter on the drive on Channel A is changed. Refer to section 8 for more information.

•

Because the MDB-100 derives its control power from the drive connected to Channel A, removing power from that drive will also cause the MDB-100 to lose power, even if power is still applied to the drive connected to channel B.

•

When only 1 drive is connected to the MDB-100, it must be connected to Channel A.

2. Feature Summary

The MDB-100 interface provides a wide array of network data access and drive control features. Combined with the flexible data access methods and universal acceptance of the Modbus network, this allows powerful networked contr ol and monitoring systems to be designed. Som e of the main features provided by the MDB-100 which allow for this control and configurability are briefly described here:

Protocol

Modbus RTU and ASCII as specified in AEG Schneider Automat ion specification “Modicon Modbus Protocol Reference Guide PI-MBUS-300 Rev. J”.

Implementation

Modbus network is optically isolated RS485 half-duplex 2-wire + shield physical layer, allowing connection of up to 32 units (masters and slave MDB-100 units) to a single bus trunk.

Network Baud Rates

Supports all Modbus RTU/ASCII baud rates f rom 300 baud to 38.4kbaud.

Drive Connections

The MDB-100 provides support for simultaneous connection of 2 VF-S7 drives. Both drives share a common Modbus station address. By supporting 2 drives per interface, the maximum number of drives that can be connected to 1 Modbus network segment without requiring r epeat ers increases from 31 (31 drives + 1 master) to 62 (31 MDB-100 units + 1 master).

Power Supply

Self-contained. Powered directly fr om the drive connected to the Channel A communications port. No external power supply devices or connections are required.

Isolation

The MDB-100 has 3 separate isolated circuitry sections. Each drive is f ully optically isolated from each other, and bot h dr ives are opt ically isolated from the Modbus network. By using optically isolated connections to the drives and the Modbus network, noise immunity is greatly impr oved and g r ounding differential pr oblem s become a thing of the past.

Drive AutoScan Algorithm

Connections to the drives are automatically established and continuously monitored. No drive configuration needs to be performed to connect the MDB-100 and communicate via the Modbus RTU or ASCII network. Just plug it in – it’s that simple.

Programmable Pointer Registers

32 programmable pointer reg ist ers are provided for user definition. By using these registers, freq uently-accessed drive parameters that may be scattered throug hout the register map can be grouped tog ether and accessed with a single holding register read or write command.

Response Delay Function

A programmable network response delay f unction is available which forces the MDB100 to wait a certain minimum time before generating network responses to Modbus commands. This function is useful when equipment such as radio modems (which require a finite time t o switch from receive to transmit mode) are used as Modbus network bridges.

Network Watchdog

A network watchdog function is available to detect if communication with the master controller has been interrupted. If an interruption is detected, several different drive actions can be programmed to ensure that t he pr ocess under control can be safely and automatically driven to a desired state.

Modbus Network Connector

The network interface is a 3- position pluggable terminal block with the following signals provided:

Pin Number Function

1 Modbus network RS485 “A” terminal 2 Modbus network RS485 “B” terminal 3 Network shield connection point

No network termination is provided on the MDB-100. Be sure to install proper RS485 network termination on the MDB-100 units that exist on the extreme endpoints of the network bus. This can be accomplished by placing a 121Ω (±5%) , 1/2W resist or across the A and B network terminals of t hose 2 unit s .

Drive Network Connectors

Uses standard RJ-45 style 8-pin modular connectors. Any standard category-5 ethernet cable (found in most electronics and office-supply stores) 5 meter s or less in length can be used to connect the MDB-100 to the drives.

Supported Commands

The MDB-100 presents and receives drive data via Modbus commands 01 (read coil status), 03 (read holding reg ist er s) , 05 (force single coil), 06 (pr eset single register) and 16 (preset multiple registers) .

3. Installing The MDB-100

The MDB-100 connects to each drive via the drive’s communication port, located on the right-hand side of the dr ive enclosure under a sm all snap- on cover. Although no drive parameters need to be configur ed in order to use the MDB-100, it is advantageous to check that the drive’s communicat ion dat a r at e is set to its maximum speed. Because the MDB-100 will communicate to each drive only at the drive’s configured data rate, t his will provide the fastest response time for dr ive-t oModbus network data transfers. For information on checking the drive’s communication data rate, refer to the appropriate manual supplied with your drive. Note that each drive’s communication data rate settings are independent of the Modbus network data rate, which is configured solely by the Modbus network characteristics switch (refer to sect ion 7) . Also not e that the data communication parameters of each drive are handled independently; the dr ive connected t o Channel A may simultaneously communicate to the MDB-100 at completely different baud rates, parity settings, etc. than the drive connected to Channel B.

Installation of the MDB-100 Modbus RTU / ASCII inter face should only be performed by a qualified technician familiar with the m aintenance and operation of the connected drives. To install the MDB-100, complete the following steps:

1. connected have been turned OFF and are locked and tagg ed out .

2. capacitors to discharge before pr oceeding to the next step.

internal parts with power applied to the drive, or for at least 5 minut es af t er power to the drive has been removed. A hazard exists temporarily for electrical shock even if the source power has been removed.

CHARGE LED has gone out before continuing the installation process.

3. Attach the MDB-100 to a sturdy, unmovable object (such as a wall) via the 2 case mounting holes located on the tabs at the t op and bottom of the enclosure.

4. Remove the drive’s communication port cover, located on the rig ht - hand side of the drive (as viewed when facing the drive), by pressing against the side of the cover while sliding it toward the front of the drive. Do not discard this cover, as it should be reinstalled if the MDB-100 unit is ever disconnected fr om t he drive.

5. Connect the drive’s communication port to Channel A of the MDB-100 with the communication cable (communication cable is not included with the MDB-100 kit). When choosing cables for this connection, standard 24 AWG category-5 (CAT 5) unshielded twisted-pair (UTP) 8-conductor cables f ound in ethernet networks in most office environments can be used. The maximum allowable length for these cables is 5 meters. Although there are many varieties and styles of CAT-5 UTP cables available, ICC strongly recommends using only high- quality cables from reputable manufacturers to guarantee optimal noise immunity and cable longevity. Ensure that each end of the cable is fully seated into the modular connector, and route the cable such that it is locat ed well away from any drive input power or motor wiring. Also take care to route the cable away from any sharp edges or positions where it may be pinched.

7. Remove the cover of the MDB-100 by removing the 4 cover screws.

8. Configure the Modbus network characteristics such as baud r at e, parity etc. via 8position DIP switch SW1 ( r efer to section 7). If the MDB-100’s station address is to be configured locally, select the desir ed st ation address via 8-position DIP switch SW2 (refer to section 8).

9. Reinstall the cover of the MDB-100.

10. Connect the Modbus network cable (2 signal wires + shield) to the 3-position pluggable terminal block m ar ked “Network” on the left-hand side of the MDB-100. The terminal ordering for the network cable wiring is as shown in Figure 1.

Note that some RS485 equipment manufacturers reference t he “ A” and “ B” terminals reversed from the MDB-100’s hardware, and some manufacturers use other labels, such as “+” and “-“. If you cannot communicate with the MDB-100 after installation, try switching t he “ A” and “ B” signal wires - swapped signal wires are the most common cause of communication difficulties in new RS485 network installations.

Ensure that the Modbus network cable is tightly screwed into the terminals, and route the cable such that it is located well away from any drive input power or motor wiring. Also take care to r out e all cables away from any sharp edges or positions where they may be pinched.

11. Take a moment to verify that the MDB-100 and all network cables have suff icient clearance from drives, motors , and power-carrying electrical wiring.

Inspection Points

• Check that the Modbus network connector screws and terminal block plug are not loose. Tighten if necessary.

• Check that the drive communication cables are not loose. Reinsert if necessary.

• Visually check all wiring and cables for damage. Replace as necessary.

• Clean off any accumulated dust and dirt.

Do not touch any internal parts with power applied

• If use of the MDB-100 is discontinued f or extended per iods of time, apply power at least once every two years and confirm that the unit still functions properly.

• Do not perform hi-pot t est s on t he drives or MDB-100 interface, as they may damage the units.

Please pay close attention to all periodic inspection points and maintain a g ood operating environment.

6. Storage And Warranty

6.1 Storage

Observe the following points when the MDB-100 interface is not used imm ediat ely after purchase or when it is not used for an extended per iod of time.

• Avoid storing the MDB-100 in places that are hot or humid, or t hat contain large quantities of dust or m etallic dust. Store the MDB-100 in a well-ventilated location.

• When not using the MDB-100 interface for an extended period of time, apply power at least once every two years and confirm that it still functions properly.

6.2 Warranty

The MDB-100 Modbus RTU / ASCII Communications Interface is covered under warranty by ICC for a period of 12 months from the date of installat ion, but not to exceed 18 months from the date of shipm ent from the factory. For further warranty or service information, please contact Industrial Control Communications or your local distributor.

7. Network Characteristics Configuration

The MDB-100 interface board uses an 8-position DIP switch (labeled SW1) to configure the Modbus network communication characteristics. The switch settings are only read during initialization, so if a chang e is m ade to any of the switches on SW1, the MDB-100 must be r eset in order to enable the new settings. The various configuration setting s of switch SW1 are as follows:

Communication Method:

A Note About Modbus Communicati on Formats

According to the Modicon Modbus Protocol Reference Guide both Modbus ASCII and RTU communication modes are as f ollows:

ASCII Mode

Coding System:

One hexadecimal character contained in each ASCII character

Bits per Byte:

7 data bits, least signif icant bit sent first 1 bit for even/odd parity; no bit for no parity 1 stop bit if parity is used; 2 bits if no parity

Error Check Field:

RTU Mode

Coding System:

Two hexadecimal characters contained in each 8-bit field of the

Bits per Byte:

8 data bits, least signif icant bit sent first 1 bit for even/odd parity; no bit for no parity 1 stop bit if parity is used; 2 bits if no parity

Error Check Field:

According to the Modicon Modbus specification, theref or e, the number of bits per byte in ASCII mode is 1 start + 7 data + 1 parity + 1 stop (if parity is used), or 1 start + 7 data + 2 stop (if parity is not used). T he ASCII data frame is therefore fixed at 10 bits per byte. Similarly, the number of bit s per byte in RTU mode is 1 start + 8 data + 1 parity + 1 stop (if parity is used), or 1 start + 8 data + 2 stop (if parity is not used), resulting in an RTU data f r am e that is fixed at 11 bits per byte.

In addition to these standard specified dat a frame sizes, the MDB-100 interface offers an optional configuration of providing for only 1 stop bit when no parity is selected in the RTU communication mode. As indicat ed on t he pr evious pag e, by setting SW5 and SW6 both to “ON”, the RTU data frame size is modified to consist of 1 start + 8 data + 1 stop bit = 10 bits per byte. Please note t hat this setting is only valid when RTU mode is selected; if SW5 and SW6 ar e both set to “ON” when ASCII mode is selected, the MDB-100 will halt and will not communicate with the Modbus network.

8. Modbus Station Address Selection

The MDB-100 interface provides two differ ent m e t hods for configuring t he node’s station address. One method uses the inverter num ber parameter read from t he drive connected to Channel A, and the other method uses a locally-configured address, set by DIP switches on the MDB-100 control PCB.

When shipped f rom the factory, the MDB-100’s default configuration is to use the value set in the inverter number parameter (F802) of the drive connected to Channel A as its Modbus network station address. Depending on the sof tware version of the drive connected to channel A, this parameter is adjustable from either 0∼31 or 0∼63.

Since Modbus addressing allows for station addresses to be set from 1 ∼ 247, however, there may be instances where the upper limit of the inverter num ber parameter setting is not hig h enough to support a desired address (for example, if you want to set a MDB-100 station to address 95) In these instances, the locallyconfigured station address can be used, which supports the full Modbus station addressing range of 1 ∼ 247.

Note that the Modbus protocol specification stat es t hat allowable station addresses are 1 to 247. If a station addr ess is configured with 0 (inverter number or local address) or 248 to 255 (local address only), the MDB-100 will halt and will not communicate with the network. To resolve this situat ion, cor rect the station number and reset the MDB-100. Pay particular attention to this point , as the default factory setting of the drive’s “inverter number ” parameter is 0, which therefore must be changed if it is to be used as the MDB-100’s station number .

The selection of whether to use the drive on Channel A’s inverter num ber par am eter or the locally-set station address is perf or m ed by switch SW1 #8. When SW1 #8 is OFF (factory default set ting), the MDB-100’s station address is retrieved from drive A’s inverter number parameter. When SW1 #8 is ON, the MDB-100’s station address is obtained by the binary number set via DIP switch SW 2 ( factory default address setting = 1).

SW1 #8 Meaning

OFF

The values of switches SW 1 and SW2 are read only during MDB-100 initialization. Therefore, if any of these switch settings are changed, the MDB-100 must be reinitialized to be made aware of the change by:

2. Issuing a reset command to the MDB-100 via the Modbus network by writing to holding register 0x6111 writing data 0xFEBA will reset the MDB-100 and return all MDB-100 –specific configuration register s (such as response delay time, loss of communications timeout time etc.) to t heir factory default values, and writing any other dat a will cause the MDB-100 to return a Modbus “ILLEGAL DATA VALUE” exception response (exception code 03). Reading fr om r egister 0x6111 will always return a value of 0.

Throughout this document, hexadecimal ( base 16) num ber s will be represented by a preceding “0x” or by a trailing “H” designator, decimal (base 10) numbers will be represented by a trailing subscripted “ 10” designator, and binary (base 2) numbers will be represented by a tr ailing “B” designator. Binary numbers will always be written with their most significant bit (MSB) at the left, and their least significant bit (LSB) to the right (next to the “B”).

For example, 0x6111 = 6111H = 24849

= 0110 0001 0001 0001B.

NOTE 2:

The Modbus specification lists two addresses for each holding register (4X

reference) and coil (0X reference). These are ref er r ed to as the “addressed as” and “known” as values. In all instances, regist er s and coils are addressed starting at zero; i.e. register 1 is addressed as 0, and coil 15 is addressed as 14, etc. Throughout this document, all addresses given for coils and holding register s will be their “ addr essed as” values unless otherwise specified. In other words, add 1 to the register/coil address given to obtain its “known as” value. For example, the S7 drive’s inverter number parameter is 0802H (= 0x0802 = 2050

.) Therefore, this

register would be “known as” 2051. Refer to t he Modbus Protocol Reference Guide for a m or e detailed explanation of this issue.

The station address set via switch SW 2 m ust be set using binary encoding. In this case, SW2 #1 repr esents bit #0 of the address, and SW2 #8 represents bit #7. When one of the DIP switches of SW 2 is turned ON, the corresponding address bit is 1, and when one of the switches is turned OFF, the corresponding addr ess bit is 0.

For example, if an address of 169

is desired, the conversion calculation would be

performed as follows:

= 0xA9 = 1010 1001B, therefore switches SW2 #1, #4, #6 and #8 should be

169

ON, and #2, #3, #5 and #7 should be OFF. Some more address configurat ion examples (factory default setting = 1) :

9.1 Supported Modbus Commands

The MDB-100 interface supports 5 Modbus commands: command 1 ( 0x01: r ead coil status), command 3 (0x03: read holding r egisters), command 5 (0x05: force single coil), command 6 (0x06: preset single register) and command 16 (0x10: preset multiple registers). Not all r egisters or coils support all commands (for example, read-only registers cannot be written to with a command 16). For more information, refer to section 10. The following limits represent the maximum number of registers and coils that can be read/written in one packet tr ansact ion:

9.2 Programmable Pointer Register Function

MDB-100 registers 0x6000 ∼ 0x601F and 0x6080 ∼ 0x609F are used as programmable pointer and data registers, respectively. Registers 0x6000 ∼ 0x601F (32 total) are used to define ot her register addresses from which you would like to read or write, and registers 0x6080 ∼ 0x609F (32 total) are the actual registers used to access the data located at the register addr esses defined in registers 0x6000 ∼ 0x601F. For example, if you would like to continuously read the data from registers 0xFE03, 0xFE04, 0xFE06, and 0xFD00, the standard register configuration would require 3 read commands to be issued: one reading 2 registers starting at r egister 0xFE03, one reading 1 register starting at register 0xFE06, and one reading 1 register starting at r egister 0xFD00. To conserve network bandwidth and speed processing time, however, the programm able point er registers can be used to allow the same information to be accessed, but by only issuing 1 comm and which reads 4 registers.

To configure this function, program as many registers as necessar y (up t o 32) in t he range 0x6000 ∼ 0x601F with the register numbers of the regist er s you would like to continuously access. In this example, we would set register 0x6000 to 0xFE03 (the first register number we want to access), register 0x6001 to 0xFE04, register 0x6002 to 0xFE06, and register 0x6003 to 0xFD00. The data located at t hese dr ive stat us registers can then be obtained by accessing the corresponding registers in the range 0x6080 ∼ 0x609F (data register 0x6080 corresponds to address register 0x6000, data register 0x6081 corresponds to address regist er 0x6001, et c. ) Therefore, the 4 registers that are to be monit or ed can now be accessed simply by issuing 1 holding register read command with a length of 4 starting from reg ist er 0x6080. T he returned

data will be the data obtained from reg ist er s 0xFE03, 0xFE04, 0xFE06, and 0xFD00 (in that order).

Note that the settings of t he pr ogrammable address registers (0x6000 ∼ 0x601F) are stored in the MDB-100’s nonvolatile EEPROM. Therefore, do not write t o any of these registers more than 100,000 t imes. Typically, these registers would only be written to once, when the interface and Modbus network are fir st commissioned. When the programmable pointer registers ar e modified, the changes are made effective in the MDB-100 immediately (the MDB-100 does not need to be r eset for the changed values to take effect).

9.3 Loss of Communications Timer Function

A configurable "loss of communications" (network watchdog) timer function is provided, which can detect communication losses and perform cert ain actions if a valid packet is not received and processed within a set time period.

MDB-100 register 0x6100 sets the loss of communication tim e value (adjustable from 100ms to 60.000s in 1ms increments, f act or y sett ing = 10.000s). If a valid (exception-free) reception-r esponse or exception- free broadcast does not take place within this time limit, the timer will expire. If the timer expires, 5 possible actions can occur for each connected drive, as set by the value of registers 0x6101 and 0xE101 (loss of communications action for drive A and drive B, respectively):

0x6101 / 0xE101

Setting

0 (default) No action: ignore timeout

1 Decelerated stop 2 Coast stop 3 Trip “E” (emergency off) 4 Run a preset speed

When a network t im eout is detected, the timeout action is perf or m ed. When communications are once again reestablished, the timer function is automatically reset and will once again begin to monitor network r ecept ions. However, any actions performed as a result of the timeout occurring will not be reversed by the MDB-100 once communications are reestablished; the Modbus master’s application m ust explicitly modify the affected condit ions t o fully return the drive to its previous state.

Setting 0 is the default setting; when a communications timeout occurs, no action will be taken.

For setting 1 (decelerated stop) , the drive will stop in a controlled manner if it was running. This action clears bit #10 in the select ed dr ive’s comm unicat ion com m and bit structure (register 0x7A00 / 0xFA00 - also the same data as write-only coil #10 / #26). Note that the “communication command valid” bit of register 0x7A00 / 0xFA00 (bit #15 of each register, or write-only coil #15 / #31) must already be set by the master application for this t im eout action to control the drive.

Action Taken Upon Timeout

For setting 2 (coast stop), the drive will coast stop (free run) if it was running . This action clears bit #10 in the selected drive’s communication command bit structure (register 0x7A00 / 0xFA00 - also the same data as write-only coil #10 / #26) and set s bit #11 (same as coil #11 / #27). Note that t he “communication command valid” bit of register 0x7A00 / 0xFA00 (bit #15 of each reg ist er , or write-only coil #15 / #31) must already be set by the master application for this t im eout action to control the drive.

For setting 3 (trip “em er gency off”), the dr ive will trip “E”. This action clears bit #10 in the selected drive’s communication command bit struct ur e ( r egister 0x7A00 / 0xFA00

- also the same data as write-only coil #10 / #26) and sets bit #12 (same as coil #12 /

#28). Note that in this case the sett ing of the “communication command valid” bit of register 0x7A00 / 0xFA00 (coil #15 / #31) is irrelevant; t he dr ive will trip regardless of its value.

Setting 4 (run a preset speed) will modif y the set t ings of bits #0 ∼ #3 of the selected drive’s communication command bit structure (register 0x7A00 / 0xFA00 - also the same data as write-only coils #0 ∼ #3 / #16 ∼ #19). The preset speed that is to run is selected by MDB-100 registers 0x6102 (for drive A) and 0xE102 (for dr ive B). The possible adjustment range for these registers is 0 ∼ 15, corresponding to “no action” (0) and each of the drive’s 15 possible preset speeds (1 ∼ 15). Note that the “communication command valid” and “run/stop” bit s of register 0x7A00 / 0xFA00 (bits #15 and #10 of each register, or write- only coil #15 & #10 / #31 & #26) m ust already be set by the master application for t his t im eout action to control the drive.

EXTREME CAUTION WHEN SELECTING THIS SETTING!

there is no possibility of personal injury or equipm ent damage due to the inverter running at the selected speed, especially with the possibility that network communications may not be able to be reestablished in a timely fa shion ( depending on what network condition caused the communications timeout in the first place).

Note that the settings of the timeout time, timeout action and timeout pr eset speed configuration regist er s are stored in the MDB-100’s nonvolatile EEPROM. Therefore, do not write to any of these registers mor e t han 100,000 times. Also note that when the setting of any one of these configuration registers is changed, the MDB-100 must be reset for the new value to be activated and the change to take effect.

Thoroughly verify that

9.4 Response Delay Timer Function

Register 0x6110 contains the setting f or a r esponse delay timer function. This function is useful for applications where it may not be desirable for the MDB-100 interface to respond immediat ely to t he net work after a read/write request, such as when a radio modem that must be switched from receive mode t o t r ansmit mode is being used.

The response delay timer is adjustable in 1ms increments from 0s to 2.000s (fact or y setting = 0s). A response delay of 0s means that there is no delay; response packets will be sent by the MDB-100 as soon as they are available. The delay timer starts when a complete packet is received by the MDB-100, and a response will not be sent until the timer has expired (at a minimum). Note that this time value only sets a minimum response delay value - depending on the quantity and location of r egisters read / written, much more time m ay actually be req uired before a complete response is formulated and ready to be returned to the network.

The response delay timer value is read only upon MDB-100 initialization, requiring the unit to be reset if the value is chang ed for the new value to take eff ect . This setting is also non-volatile (written to the MDB-100’s EEPROM). Ther efore, do not write to this register more than 100, 000 t im es.

10. Modbus Programming Interface

10.1 Overview

Three types of Modbus data may be accessed via the MDB-100. These are holding registers (4x reference), read-only coils (0x reference) and write-only coils (0x reference). In order to access 2 drives within the allocated holding register map (0x0000 ∼ 0xFFFF), each drive is assigned one half of the register space.

Drive A occupies the area from regist er 0x0000 to 0x7FFF. T his ar ea also contains several network and drive configuration registers (such as the programmable point er and data registers, network timeout r egisters, etc.) that reside within the MDB-100 only. The registers which the MDB-100 uses for these funct ions ar e not accessible in the drive. Currently, these register s ar e unoccupied in t he drive, and therefore no loss of access to any drive parameters exists. Most of the registers for drive A are mapped to the exact same “communication number” that they are allocated in the S7 drive by Toshiba. Refer to the VF-S7 Serial Com m unicat ions O ption Manual for a list of communication numbers. T he only exception to this direct mapping are the registers that occupy communication numbers larger than 0x8000. For these parameters, their corresponding Modbus holding registers can be obtained by setting the MSB (bit #15) of their communicat ion number to 0.

For example, the communication number f or drive A’s bus voltage parameter is 0xFE04 (1111 1110 0000 0100B). Setting bit #15 to 0, we obtain the binary value 0111 1110 0000 0100B, or 0x7E04. Reading from Modbus holding reg ist er 0x7E04 (“known as” 0x7E05), therefor e, will return the bus voltage from drive A.

Drive B occupies the area from regist er 0x8000 to 0xFFFF. T his ar ea also contains the MDB-100 –specific drive configuration registers that correspond to those available for drive A. Most of the register s for drive B are not mapped to the exact same “communication number” that t hey are allocat ed in the S7 drive by Toshiba. For these parameters, their corresponding Modbus holding registers can be obtained by setting the MSB (bit #15) of their com m unicat ion num ber to 1.

For example, the communication number f or drive B’s deceleration time #1 parameter is 0x0010 (0000 0000 0001 0000B). Setting bit #15 t o 1, we obtain the binary value 1000 0000 0001 0000B, or 0x8010. Writing to Modbus holding register 0x8010 (“known as” 0x8011), therefore, will modify the deceleration time #1 parameter for drive B.

The only exception to this mapping modificat ion r equirement for drive B are the registers that occupy communication numbers larger than 0x8000. For these parameters, the communication number s given in the VF-S7 Serial Communications Option Manual correspond exactly to their assigned “addressed as” holding registers (for example, holding reg ist er 0xFE10 will access the past tr ip #1 value from drive B).

Refer to Figure 2 on page 20 for a graphical representat ion of the holding register mapping that exists in the MDB-100 Modbus interface.

Sections 10.2 to 10.4 specify the communication num ber → holding register mappings and coil definitions fo r all cur r ent VF-S7 communication numbers. Note that the parameters and coils shown are those available at the time of this manual printing; if new parameters ar e added by the dr ive manufacturer and/or parameter adjustment limits are modified, etc., this will not affect the operation of the MDB-100 interface. As all available parameters, adjustment ranges etc. are det er mined solely by the connected drive, and not the MDB-100, future drive firmware versions will automatically be supported by the MDB-100 with no software upgrades required.

In the case of any discrepancies between the informat ion in t he following tables and the drive’s documentation, the drive’s documentation should always be followed.

Some other important coil and holding r egister notes:

• Remember that all registers and coils indicated in the following sections are shown with their “addressed as” coil & register numbers. T hese coil & register numbers are 1 less than their “ known as” numbers.

• A value indicated by “*” in the following tables indicates that t he set ting is dependent on the connected drive’s capacity. Refer to the drive’s documentation for these values.

• If frequency command values (r egisters 0x7A01 / 0xFA01) higher than each respective drive’s FH or UL parameters are written, the write will be acknowledged, but the drive will not change its f r equency to this invalid value.

• All writes to holding registers use the drive’s RAM / EEPROM data write (“W”) command except for registers 0x7A00 ∼ 0x7A02 and 0xFA00 ∼ 0xFA02, which use the drive’s RAM data write (“P”) command.

• If an attempt is made to access non- existent r egisters or coils, an ILLEGAL DATA ADDRESS exception (code 02) will be returned.

• If an attempt is made to write invalid data to a register or coil, an ILLEG AL DATA VALUE exception (code 03) will be returned.

• If a drive connected to the MDB-100 goes “offline”, all coils will hold their last state, with the exception of read-only coils #115 and/or #131, which will indicate “offline”. O nce communication with the drive(s) is reestablished, these coil(s) will again indicate “online”.

• If a drive connected to the MDB-100 goes “of fline”, attempts to access any register in that drive’s regist er space will return a Modbus “SLAVE FAILURE” error (code 04), except for t he following registers, which will hold their last state:

1. Communication command (communication number FA00)

2. Communication frequency command (communication number FA01)

3. Output frequency (comm unication number FD00)

4. Status (communication number FE01)

5. Output current (communicat ion num ber FE03)

6. Output voltage (communication num ber FE05)

• Note that the MDB-100 does not assign drive register and coil functions; they are entirely drive-dependent, and managed by the drive manuf acturer.

• Each drive’s write-only coils are mapped to the corresponding drive’s communication command parameter (com munication number #FA00). Also,

the MDB-100 does not place any restrictions on coils marked as “Reserved”. These coils may be written to at any time. The data or function associated with these coils is entirely defined by the connected drive.

• With the exception of coils #115 and #131, each drive’s read-only coils are mapped to the corresponding drive’s communication stat us register (communication number #FE01). Also, t he MDB-100 does not place any restrictions on coils marked as “Reserved”. These coils may be read from at any time. The data or function associated with these coils is ent irely defined by the connected drive.
