Communication
Cassette
-
Features
1. Communications function added to FP SIGMA
to save space.
Since the communication cassette fits inside the
FP SIGMA Control Unit, a communications function can be added
without consuming space on control boards.
2. Type also available with RS232C × 1ch and
RS485 × 1ch.
Distributed control (RS485 data transmission)
using linked PLCs, etc., is possible while using RS232C to
communicate with standalone devices
(for example an Image checker).

Notes 1) In order to use the serial communication
function (1:N communication), a RS485 type communication cassette
is required.
2) The transmission speed (baud rate) and
transmission format are specified using the system registers.
3) Unit (station) numbers are specified using the
system registers. Up to 31 units (stations) can be set, using the
switches on the control unit.
4) When connecting a commercially available device
that has an RS485 interface, please confirm operation using the
actual device. In some cases, the number of units (stations),
transmission distance, and transmission speed (baud rate) vary
depending on the connected device.
5) The values for the transmission distance,
transmission speed (baud rate), and number of units (stations)
should be within the values noted in the graph below.
