Asynchronous serial links
TSX Micro/Premium PLCs provide, via their processor, coprocessor or
TSX SCY 21601 communication module, several possible ways for exchanging data
in character mode with devices equipped with an asynchronous serial link interface:
b RS 485 integrated port.
b Type III PCMCIA card with RS 232D, RS 485 (RS 422 compatible) or 20 mA
current loop link.
Protocols supported are character mode (ASCII), Uni-Telway and Modbus.
Other protocols are also available, or can be developed on request, on a RS 485 or
RS 232D link, which enables TSX Micro/Premium PLCs to communicate on
third-party architectures. These products are offered within the framework of the
Schneider Alliances partnership programme. The list of modules available can be
obtained from your Regional Sales Office, or from our Internet site
www.schneideralliances.com.
1 Via integrated port on the processor or coprocessor
The AUX (1) port (8-way mini-DIN connector) has one non-isolated RS 485 serial link
channel (maximum distance 10 m).
2 Via integrated port on the TSX SCY 21601 module
This module for Premium PLCs has one isolated RS 485 serial link channel (25-way
SUB-D connector). Half duplex multiprotocol, including Uni-Telway.
3 A slot on the processor, coprocessor and on the TSX SCY 21601 module takes
cards which comprise:
4 A removable cover with fixing screws for access to the 20-way miniature
connector.
5 Two indicator lamps:
v ERR lamp: card or link fault,
v COM lamp: data transmission or reception.
Connector cable to be ordered separately:
TSX SCP Cpppp cable.
(1) TER port for TSX Micro TSX 37 05/08/10 PLC.
