Operation

TSX SCY 11601 Module: General

The TSX SCY 11601 module manages a communication channel (channel 0):

channel 0: Modbus protocol on an RS 485 half duplex isolated, standardized physical link, with a speed limited to 19200 bits per second

TSX SCY 21601: General

The TSX SCY 21601 module manages two independent communication channels, which each have their own functions:

Channel 0 deals with Uni-Telway, Modbus, and Character Mode protocols on an isolated physical link and also with standardized RS 485 half duplex with a speed limited to 19200 bits per second.
Channel 1 receives one of the following PCMCIA communication cards:
- Field Bus: TSX SCP 111 (RS232), TSX SCP 112 (current loop), TSX SCP 114 (RS 422/RS 485) Uni-Telway, Modbus, and Character mode cards
- Cell network: TSX FPP 20 Fipway card

The choice of PCMCIA card and protocol is made when the TSX SCY 21601 module's communication channels are configured using Control Expert software.
