2.3 Operation and Maintenance of the Rosemount 752

2.3.1 Set switches

Security (write protect)

Changes can be prevented to the indicator configuration data with the write protection Plantweb housing switches. Security is controlled by the security (write protect) switch/jumper located on the interface assembly or terminal block. Position the switch/jumper in the “ON” position to prevent accidental or deliberate change of configuration data.

If the indicator write protection switch/jumper is in the “ON” position, the indicator will not accept any “writes” to its memory. Configuration changes cannot take place when the indicator security is on.

To reposition the switches/jumpers, follow the procedure described below. (Simulate = Fieldbus protocol)

1. Set the loop to manual and remove power.

2. Remove the electronics compartment cover, opposite the field terminal side on the PlantWeb housing. Do not remove the indicator covers in explosive atmospheres when the circuit is live.

3. Slide the security and simulate switches into the preferred position by using a small screwdriver.

Re-install the indicator cover. Indicator covers must be fully engaged to meet explosion-proof requirements.

A. Security B. Alarm/simulate

2.3.2 Connect wiring and power up

Wiring for Fieldbus protocol

1. Remove the housing cover on terminal compartment side. Do not remove the cover in explosive atmospheres when the circuit is live. Signal wiring supplies all power to the indicator.

2. Connect the power leads to the terminals marked “FIELDBUS WIRING” as shown in Figure 2-2. The power terminals are not polarity sensitive.

3. Plug and seal unused conduit connections on the indicator housing to avoid moisture accumulation in the terminal side. If you do not seal unused connections, mount the indicator with the electrical housing positioned downward for drainage. Install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections and the indicator housing.

Electrical considerations

Configuration

January 2018

Proper electrical Operation and Maintenance is necessary to prevent errors due to improper grounding and electrical noise. Shielded, twisted pair cable should be used for best results in electrically noisy environments. Cable Type A is recommended by F

OUNDATION Fieldbus.

Power supply

The indicator requires between 9 and 32 V dc (9 and 15 V dc for FISCO) to operate and provide complete functionality. The dc power supply should provide power with less than 2% ripple.

Power conditioner

A fieldbus segment requires a power conditioner to isolate the power supply filter and decouple the segment from other segments attached to the same power supply.

Grounding

Signal wiring of the fieldbus segment can not be grounded. Grounding out one of the signal wires will shut down the entire fieldbus segment.

Shield wire ground

To protect the fieldbus segment from noise, grounding techniques for shield wire usually require a single grounding point for shield wire to avoid creating a ground loop. The ground point is typically at the power supply.

Surges/transients

The indicator will withstand electrical transients of the energy level usually encountered in static discharges or induced switching transients. However, high-energy transients, such as those induced in wiring from nearby lightning strikes, can damage the indicator.

Optional transient protection terminal block

The transient protection terminal block can be ordered as an installed option (Option code T1 in the indicator model number) or as a spare part. The spare part number is 03151-4134-0002. The lightning bolt symbol shown identifies it as a transient protection terminal block.

2.4 General considerations

2.4.1 Tagging

Commissioning (paper) tag on a fieldbus segment

When commissioning more than one device on a Fieldbus segment, it can be difficult to identify which device is at a particular location. A removable tag provided with the indicator can aid in this process by linking the Device ID and a physical location. The Device ID is a unique code that identifies a particular device in the absence of a device tag. The device tag is used by the customer as an operational identification for the device and is usually defined by the Piping and Instrumentation Diagram (P & ID).

The installer should note the physical location in both places on the removable commissioning tag and tear off the bottom portion. This should be done for each device on the segment. The bottom portion of the tags can be used for commissioning the segment in the control system, providing a direct link between the Device ID and the tag location.

Configuration

January 2018

2.5 Hazardous locations

Config uration

The Rosemount 752 Remote Indicator has explosion-proof housing and circuitry suitable for intrinsically safe and non-incendive operation. Individual indicators are clearly marked with a tag indicating the certifications they carry.

Note

Once a device labeled with multiple approvals is installed, it should not be reinstalled using any other approval type(s). Permanently mark the certification label to distinguish the installed approval type from unused approval types.

Page 14

Configuration

January 2018

2.5.1 Grounding the indicator case

Always ground the indicator case in accordance with national and local electrical codes. The most effective indicator case grounding method is a direct connection to earth ground with minimal impedance. Methods for grounding the indicator case include:

 Internal ground connection: The internal ground connection screw is inside the terminal side of the

electronics housing. The screw is identified by a ground symbol ( ), and is standard on the Rosemount 752 Remote Indicators.

 External ground assembly: Ground screw is located at the bottom of the mounting bracket.

Note

Grounding the indicator case using the threaded conduit connection may not provide a sufficient ground. The transient protection terminal block (Option Code T1) will not provide transient protection unless the indicator case is properly grounded. Use the above guidelines to ground the indicator case. Do not run transient protection ground wire with signal wiring; the ground wire may carry excessive current if a lightning strike occurs.

2.6 General block information

Reference Manual

00809-0100-4377, Rev CA

2.6.1 Modes

The Resource, Transducer, and all function blocks in the device have modes of operation. These modes govern the operation of the block. Every block supports both automatic (AUTO) and out of service (OOS) modes. Other modes may also be supported.

Changing modes

To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the block is operating properly.

Permitted modes

It is possible to prevent unauthorized changes to the operating mode of a block. To do this, configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is recommended to always select OOS as one of the permitted modes.

Types of modes

For the procedures described in this manual, it will be helpful to understand the following modes:

AUTO

The functions performed by the block will execute. If the block has any outputs, these will continue to update. This is typically the normal operating mode.

Out of service (OOS)

The functions performed by the block will not execute. If the block has any outputs, these will typically not update and the status of any values passed to downstream blocks will be “BAD”. To make some changes to the configuration of the block, change the mode of the block to OOS. When the changes are complete, change the mode back to AUTO.

In this mode, variables that are passed out of the block can be manually set for testing or override purposes.

Other types of modes

Other types of modes are Cas, RCas, ROut, IMan and LO. Some of these may be supported by different function blocks in the Rosemount 752. For more information, see the Function Block Reference Manual

Note

When an upstream block is set to OOS, this will impact the output status of all downstream blocks. The figure below depicts the hierarchy of blocks:

2.6.2 Link active scheduler (LAS)

Configuration

January 2018

The Rosemount 752 can be designated to act as the backup LAS in the event that the LAS is disconnected from the segment. As the backup LAS, the Rosemount 752 will take over the management of communications until the host is restored.

The host system may provide a configuration tool specifically designed to designate a particular device as a backup LAS. Otherwise, this can be configured manually as follows:

1. Access the Management Information Base (MIB) for the Rosemount 752.

2. To activate the LAS capability, write 0x02 to the BOOT_OPERAT_FUNCTIONAL_CLASS object (Index

605). To deactivate, write 0x01.

3. Restart the processor.

2.6.3 Block instantiation

Rosemount devices are pre-configured with function blocks at the factory, the default permanent configuration for the Rosemount 752 is listed below. The Rosemount 752 can have up to nine additional instantiated function blocks.

 1 Proportional/integral/derivative block (tag name PID_1600)  1 Input selector block (tag name ISEL_1700)  1 Signal characterizer block (tag name CHAR_1800)  1 Arithmetic block (tag name ARITH_1900)  1 Integrator block (tag name INTEG_2000)

The Rosemount 752 supports the use of Function Block Instantiation. When a device supports block instantiation, the number of blocks and block types can be defined to match specific application needs.The number of blocks that can be instantiated is only limited by the amount of memor y within the device and the block types that are supported by the device. Instantiation does not apply to standard device blocks like the Resource and LCD Transducer Block.

Config uration

By reading the parameter “FREE_SPACE” in the Resource block you can determine how many blocks you can instantiate. Each block that you instantiate takes up 4.5573% of the “FREE_SPACE”.

January 2018

Block instantiation is done by the host control system or configuration tool, but not all hosts are required to implement this functionality. Please refer to your specific host or configuration tool manual for more information.

OUNDATION Fieldbus protocol” Product Data Sheet available on Emerson.com/Rosemount-3051S.

Reference information on the ISEL, INT, ARTH, SGCR and PID blocks can be found in the Function Block

Reference Manual

Resource block (1000)

The Resource block contains diagnostic, hardware and electronics information. There are no linkable inputs or outputs to the Resource Block.

LCD transducer block (1100)

The LCD Transducer Block is used to configure the LCD meter.

PID block (1200)

The PID Function Block combines all of the necessary logic to perform proportional/integral/derivative (PID) control. The block supports mode control, signal scaling and limiting, feed forward control, override tracking, alarm limit detection, and signal status propagation.

Configuration

January 2018

The block supports two forms of the PID equation: Standard and Series. You can select the appropriate equation using the MATHFORM parameter. The Standard ISA PID equation is the default selection.

Input selector block (1300)

The Input Selector (ISEL) Function Block can be used to select the first good, Hot Backup, maximum, minimum, or average of as many as eight input values and place it at the output. The block supports signal status propagation.

Signal characterizer block (1400)

The Signal Characterizer (SGCR) Function Block characterizes or approximates any function that defines an input/output relationship. The function is defined by configuring as many as twenty X,Y coordinates. The block interpolates an output value for a given input value using the curve defined by the configured coordinates. Two separate analog input signals can be processed simultaneously to give two corresponding separate output values using the same defined curve.

Arithmetic block (1500)

The Arithmetic (ARTH) Function Block provides the ability to configure a range extension function for a primary input. It can also be used to compute nine different arithmetic functions.

Integrator block (1600)

The Integrator (INT) Function Block integrates one or two variables over time. The block compares the integrated or accumulated value to pre-trip and trip limits and generates discrete output signals when the limits are reached.

2.8.1 FEATURES and FEATURES_SEL

The parameters FEATURES and FEATURE_SEL determine optional behavior of the Rosemount 752.

FEATURES

The FEATURES parameter is read only and defines which features are supported by the Rosemount 752. Below is a list of the FEATURES the Rosemount 752 supports.

UNICODE

All configurable string variables in the Rosemount 752, except tag names, are octet strings. Either ASCII or Unicode may be used. If the configuration device is generating Unicode octet strings, you must set the Unicode option bit.

REPORTS

The Rosemount 752 supports alert reports. The Reports option bit must be set in the features bit string to use this feature. If it is not set, the host must poll for alerts.

Reference Manual

00809-0100-4377, Rev CA

SOFT W LOCK and HARD W LOCK

Inputs to the security and write lock functions include the hardware security switch, the hardware and software write lock bits of the FEATURE_SEL parameter, the WRITE_LOCK parameter, and the DEFINE_WRITE_LOCK parameter.

The WRITE_LOCK parameter prevents modification of parameters within the device except to clear the WRITE_LOCK parameter. During this time, the block will function normally updating inputs and outputs and executing algorithms. When the WRITE_LOCK condition is cleared, a WRITE_ALM alert is generated with a priority that corresponds to the WRITE_PRI parameter.

The FEATURE_SEL parameter enables the user to select a hardware or software write lock or no write lock capability. To enable the hardware security function, enable the HW_SEL bit in the FEATURE_SEL parameter. When this bit has been enabled the WRITE_LOCK parameter becomes read only and will reflect the state of the hardware switch. In order to enable the software write lock, the SW_SEL bit must be set in the FEATURE_SEL parameter. Once this bit is set, the WRITE_LOCK parameter may be set to “Locked” or “Not Locked.” Once the WRITE_LOCK parameter is set to “Locked” by either the software or the hardware lock, all user requested writes as determined by the DEFINE_WRITE_LOCK parameter shall be rejected.

The DEFINE_WRITE_LOCK parameter allows the user to configure whether the write lock functions (both software and hardware) will control writing to all blocks, or only to the resource and transducer blocks. Internally updated data such as process variables and diagnostics will not be restricted by the security switch.

Modes

The resource block supports two modes of operation as defined by the MODE_BLK parameter:

Automatic (Auto)

The block is processing its normal background memory checks.

Out of service (OOS)

The block is not processing its tasks. When the resource block is in OOS, all blocks within the resource (device) are forced into OOS. The BLOCK_ERR parameter shows Out of Service. In this mode, changes can be made to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes.
