FAQ
-
Does the FC-DCOM-234/485 module support MODBUS RTU in both master and slave configurations?
Yes, the module can be configured to act as either a MODBUS master or slave depending on application needs. -
Can the module communicate over both RS-232C and RS-485 simultaneously?
No, only one port is active at a time based on configuration. You must choose either RS-232C or RS-485 during setup. -
Is the RS-485 port electrically isolated from the system bus?
Yes, optical isolation is provided to prevent noise and protect against ground loops. -
Can I update firmware remotely?
Yes, firmware can be upgraded using Honeywell engineering tools connected to the host controller or system. -
How many devices can be connected on the RS-485 line?
The module can support up to 32 devices per RS-485 bus, following standard RS-485 limitations. -
Are custom baud rates supported?
The module supports standard baud rates between 300 and 115.2 kbps. Some custom rates may work if aligned with configuration tools. -
Is this module supported in ControlEdge RTU and PLC platforms?
Yes, it is compatible with both ControlEdge PLC and RTU systems. -
How is the communication port configured?
Port parameters (baud rate, parity, stop bits) are s/tware-configurable via system configuration tools. -
Does the module support HART communication?
No, HART communication is not supported via RS-232/485. Use dedicated HART I/O modules for that purpose. -
What happens if the module fails during operation?
Failover or module replacement can be performed with minimal impact due to hot-swap support, depending on controller setup.
