2/11 Presentation, description (continued) Modicon M580 automation platform Modicon X80 performance EIO adapter Presentation An M580 Ethernet RIO (EIO) architecture with Modicon X80 I/O drops requires the use of a dedicated adapter in each Modicon X80 drop. The BMECRA31210 adapter supports Ethernet and X-bus communications across the remote backplane. This EIO adapter module supports several expert modules such as counter and weighing modules and CCOTF (change configuration on the fly). For Modicon X80 RIO drops on an Ethernet backplane, time stamping can be managed with a resolution of 10 ms when using a BMECRA31210 performance EIO adapter. Only one BMECRA31210 module can be installed per Modicon X80 RIO drop. This module can also support a BMXXBP pp 00 expansion rack. The BMECRA31210 adapter is designed to be installed on an Ethernet backplane in the main remote rack. The adapter supports the Modicon X80 I/O and partner modules with both Ethernet and X-bus connections (1) . The keying pin on the rear side of the module means the BMECRA31210 adapter cannot be installed on unsupported backplanes. These adapters are connected by Ethernet cordsets fitted with RJ45 connectors. The dual Ethernet connection port on each adapter allows daisy chain loop connections using the RSTP protocol (Rapid Spanning Tree Protocol). The BMECRA31210 adapter is also available in a conformal coating version for harsh environments.
