1 Modbus

1.1 Modbus tm Overview

This section pr ovides basic info rmation for interfacing the Integra to a Modbus information or more details of the Integra implementation is required please refer to our “Guide to RS485 Communications and the Modbus supplier. Integra offers the option of an RS485 communication facility for direct connection to SCADA or other communications systems using the Modbus format for the master's query by placing into it the device address, a function code defining the requested action, any data to be sent, and an error check ing fie ld . The slave's re spon se me ssage is also constructed using Modbus returned, an d an error-checking field. If an er r or occurs in receipt of the message, Integra will ma ke no response. If the I ntegra is unable to p erform the requested action, it will constr uct an error message and send it as it’s response. The electrical interface is 2-wire RS485, via 3 screw terminals. Connection should be made using twisted pair screened cable (Typically 22 gauge Belden 8761 or equivalent). All "A" and "B" connections are daisy chained together. The screens should also be connected to th e “Gnd” terminal. To avoid the possibility of loop currents, an Earth connection should be made at only one point on t he network. Line topology may or may not require terminating loads depending on the type and leng th of cable used. Loop (ring) topology does not require any termination load. The impedance of the termination load should match the impedance of the cable and be at both ends of the line. The ca ble should be terminated at each end with a 120 ohm (0.25 Watt min.) resistor. A total maximum length of 3900 feet (1200 metres) is allowed for the RS485 network. A maximum of 32 electrical nodes can be connected, including the controller. The address of each Integra can be set to any value between 1 and 247. Broadcast mode (address 0) is not supported . The maximum latency time of an Integra is 150ms i. e. this is the amount of time that can pass before the first response ch aracter is output. The supervisory programme must allow t his period of time to elapse before assuming that the Integra is not going to respond. The format for each byte in RTU mode is: Coding System: 8-bit per byte Data Format: 4 bytes (2 regist ers) per parameter.

Error Check Field: 2 byte Cyclical Redundancy Check (CRC) Framing: 1 start bit

Data Transmission speed is selectable between 2400, 4800, 9600 and 19200 baud.

1.2 Input Registers

Input register s are used to indicate the present values of the measured an d calculated electrical quantities. Each parameter is held in two consecutive 16 bit registers. The following table details the 3X re gister address, and the va lues of the address bytes within the message. A tick (√) in the column indicates that the parameter is valid for the particular wiring system. Any parameter with a cross (X) will return the value Zero. Each parameter is held in the 3X registers. Modbus . For example, to request: Amps 1 Start address = 0006 No of registers = 0002 Amps 2 Start address = 0008 No of registers = 0002

Each request for data must be restricted to 40 parameters or less. Exceedi ng the 40 parameter limit will cause a Modbus

exception code to be returned.

Function Code 04 is used to access all para meters

r/w = read/write r/wp = read and write with password clearance ro = read only wo = write onl y Some registers marked wo above may in fact be read, but the value returned is not valuable. It is perfectly feasible to change Integra set-up using a general purpose Modbus easier to use the Integra disp lay or Integra configurator software. The Integra configurator software has facilities to store configurations to disk for later retrieval and rapid set up of similarly configur ed products.

Password Settings marked r/wp require the instrument password to have been entered into the Password register before changes will be accepte d. Once the instrumen t configuration has been modified, the password should be written to the pa ssword register again to protect the configuration from unauthorised or accidental cha nge. Power cycling also restores prot ection. Reading the Password register retur ns 1 if the instrument is unprotected and 0 if it is protected from changes.

* Demand Time

accomplish this. Writing any other value will cause an error to be retu r ned. Reading this register after instrument restart or resetting demand period gives the number of minutes of demand data up to a maximum of the demand period setting. For example, with 15 minute demand period, from reset the value will increment from zero every mi nute until it reaches 15. It will remain at this value until a subsequent reset occurs.

Demand Period

Writing any other value will caus e an error to be returned. System Voltage in a PT/VT connected system represents the PT/VT primary voltage. In a direct
