FAQs
Q1: What is the primary function of the 3500/92-01-00-00?
It is a Communication Gateway Module that collects static data, alarm events, and module statuses from the 3500 rack's high-speed internal network and transmits them to external systems (DCS, PLC, SCADA) via Modbus protocols. The -01-00-00 configuration uses the 136188-02 I/O module for Modbus RS485 serial communication.
Q2: What is the difference between the -01-00-00 and -03-00-00 configurations?
The -01-00-00 uses the Modbus RS485 I/O Module (136188-02) for serial communication only. The -03-00-00 uses the Ethernet/RS232 Modbus I/O Module (136188-01), providing both Ethernet TCP/IP (Modbus TCP) and RS232 serial connectivity.
Q3: How many hosts can the 3500/92 communicate with simultaneously?
The Communication Gateway can communicate via Ethernet with up to six hosts. Only one Comm Gateway module per rack can be configured to accept Rack Configuration or Data Acquisition hosts.
Q4: Is the 3500/92 hot-swappable?
Yes, the module may be installed into or removed from the rack while power is applied. However, communication with the external device (DCS, PLC, etc.) will be lost when the module is removed.
Q5: What is the difference between the 3500/90 and 3500/92?
The 3500/92 has the same communication interfaces and protocols as the 3500/90, except that the 3500/92 features a Configurable Modbus Register utility that provides the same functionality as the Main Value Modbus registers. This allows users to optimize communications by assigning the most important data to contiguous registers.
