|---|---|
| Interface | Four serial I/O ports, individually configurable for RS-232, RS-422, or RS-485 |
| Port Configuration | Ports 1, 2, 3, and/or 4 can form a single logical port with redundant cables for dual-ported devices |
| Bus Characteristics | - RS-232: DB-25 cable to customer-supplied device/modem/converter - RS-422: 4-wire medium - RS-485: Twisted-pair shielded copper cable with single conductor pair |
| Communication | Asynchronous, direct connect (RS-232); 8-bit characters; odd, even, or no parity; 1 or 2 stop bits |
| Transmission Rate | 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 baud |
| I/O Capacity | Up to 64 devices (RS-485, 16 per port) or 4 direct-connect RS-232/RS-422 devices; up to 2000 DCI point connections |
| Data Types | 2-byte or 4-byte signed/unsigned integers, 4-byte IEEE single-precision floating values, binary values; driver-dependent conversions |
| Fastest ECB Block Period | 500 ms |
| Redundancy | Pair of FBM231 modules (Master and Tracker); automatic role switching on fault detection (e.g., heartbeat) or manual via SMDH |
| I/O Drivers | Downloadable software drivers from protocol library; custom drivers available |
| Control Blocks | Supports DCI blocks: BIN, BINR, BOUT, IIN, IOUT, PAKIN, PAKOUT, PLSOUT, RIN, RINR, ROUT, STRIN, STROUT |
| Channel Isolation | Galvanically isolated, referenced to earth; withstands 600 V AC for 1 minute (not for permanent connection) |
| Fieldbus Communication | Interfaces with FCM100Et, FCM100E, FCP270, or FCP280 via redundant 2 Mbps module Fieldbus |
| Visual Indicators | LEDs for operational status, communication activity (transmit/receive per port), and Master/Tracker status |
