Installation
General
Maximum number of modules
The TSX SCY 11601/21601 modules can be installed in a Premium/Atrium PLC station rack.
They are part of an X-WAY network architecture based on Series 7, Micro, Premium and Atrium PLCs.
The TSX SCY 11601 communication module brings the following to a PLC station: l A JBUS/MODBUS isolated mono-protocol RS 485 communication channel.
The TSX SCY 21601 communication module brings the following to a PLC station: l l
A multi-protocol isolated RS 485 communication channel.
A standard PCMCIA communication card slot.
The TSX SCY 11601/21601 modules can be installed in any available slot in a
Premium/Atrium PLC station rack.
A TSX SCY 11601 module supports up to a maximum of 1 application-specific communication channel, namely the RS 485 channel built into the module.
A TSX SCY 21601 module can support a maximum of 2 application-specific communication channels, a built-in RS 485 channel and a channel from the PCMCIA card which can be integrated into the module.
Since the maximum number of application-specific channels managed by a PLC station depends on the type of processor installed, the number of TSX SCY 11601 l l
or TSX SCY 21601 modules in a station will therefore rely on:
The type of processor installed.
The number of application-specific channels already used, other than communication channels.
Consequently, the user must perform an evaluation on his/her PLC station to find out how many application-specific channels are already in use, and thus determine the number of TSX SCY 11601 or TSX SCY 21601 modules which may be used.
Note: Application-specific channel recognition is defined in the Installation Manual for Premium TSX DM 57 PLCs_Volume 1.

Connection/
Disconnection
TSX SCY 11601/21601 modules can be connected or disconnected whilst the
power is on. These devices do not have a memory save function.
When one of the two modules is disconnected from the rack, its internal memory is erased. The module goes through an initialization phase once it is reconnected.
A TSX SCY 21601 module which has a PCMCIA card installed may be disconnected when the power is on.
Note: However, PCMCIA cards, used in TSX SCY 21601 may not be
disconnected while the power is on.
