FAQ
Q1: What is the function of the Foxboro FBM230 RH926GH Compression Screw Terminal Assembly?
A1: The RH926GH provides the field wiring interface for the Foxboro FBM230 serial communication module. It allows field devices to connect to the DCS through organized terminal connections, helping technicians manage serial communication wiring and perform maintenance more efficiently.
Q2: What is the difference between the FBM230 model and the RH926GH order number?
A2: FBM230 identifies the field device system integrator module, while RH926GH is the order number for its compression screw termination assembly. They are related components but serve different purposes: the FBM230 handles serial communication, and the RH926GH provides the physical field wiring connections.
Q3: Which communication interfaces can be connected through the RH926GH?
A3: The termination assembly supports RS-232, RS-422, and RS-485 connections. RS-232 devices connect through DB-25 connectors, while RS-422 and RS-485 field wiring uses compression screw terminals. The appropriate connection method depends on the interface and wiring configuration of the connected equipment.
Q4: How many serial communication channels can the assembly support?
A4: The RH926GH provides connection facilities for up to four serial communication channels associated with the FBM230. Each channel can be wired according to the requirements of the connected field device and selected serial interface.
Q5: What is the purpose of the jumpers supplied with the RH926GH?
A5: The assembly is supplied with eight jumpers used to connect RS-422 and RS-485 signals between screw terminals. Correct jumper placement is important for establishing the intended signal paths. Always follow the terminal markings and the wiring diagram for the specific application.
Q6: How should RS-422 and RS-485 termination resistors be configured?
A6: The termination assembly provides selectable termination resistor functions for RS-422 and RS-485 connections. For RS-485 networks, termination is generally required at the physical ends of the bus to reduce signal reflections. The correct setting depends on the network topology, cable characteristics, and device position. Avoid enabling termination at every node.
Q7: What cable should be used to connect the RH926GH to the FBM230?
A7: A Type 5 termination cable is used between the FBM230 module and the RH926GH assembly. Available cable lengths range from 1 m to 5 m. For field-device connections, cable selection and maximum length depend on the serial interface: RS-232 supports up to 15 m with custom cables, while RS-422 and RS-485 can support distances of up to 1,200 m under suitable installation conditions.
Q8: What should be checked if a connected serial device cannot communicate with the FBM230?
A8: Start by checking the field wiring and ensuring that all compression screws are properly tightened. Verify the RS-232, RS-422, or RS-485 wiring configuration, jumper positions, and termination resistor settings. Then inspect the Type 5 cable between the termination assembly and the FBM230. If the wiring is correct, check the connected device’s communication parameters, including baud rate, parity, data bits, and stop bits, and review the FBM230 diagnostics for communication errors.
