Presentation (continued)

Components of an high-availability system (continued) Modicon X80 Communication modules An high-availability architecture may require the use of one or several Modicon X80 communication modules: b BMENOS0300 network option switch v to connect Primary and Standby PLCs to each other and create the redundant Ethernet link v to connect an Ethernet network to the Ethernet backplane of the local rack v to attach a DIO ring to the main ring (up to 64 distributed devices) b BMXNRP0201 fiber converter module v to connect Primary and Standby PLCs to each other and create the redundant Ethernet link through fiber optic cabling (for long-haul system) b BMXNOE0100 module for Ethernet Modbus TCP (requires BMXPRA0100 adapter) Modicon X80 I/O expansion modules In an high availability system, BM●CRA31210 I/O expansion module is used for: b connecting distributed devices (via SERVICE port) to a Modicon X80 RIO drop b forwarding messages to the CPUs, including Modbus messages received by BMXNOM0200 module b Time stamping at the source of any discrete I/O signal located in the drop with a resolution of 10 ms (NTP protocol); for higher time stamping performances (1 ms), BMXERT1604T may be used either in an RIO drop or in a local rack equipped with a BM●CRA31210 module (see Time stamping performance comparison table below) Modicon Switches Modicon Managed switches MCSESM ●●●●●●●● are used to isolate dual networks one from the other and to expand the system including Modicon X80 RIO drops, secondary rings, Ethernet DIO device cloud, or distributed equipment, while keeping the redundant network available, thanks to the switch management capabilities and multiple connection ports. Refer to Modicon Networking catalog for more details.
