7.5.4 1:N Communication (General-purpose Serial Communication)
Overview
The FP
Σ
and the external units are connected using an RS485 cable. Using the protocol that matches
the external units, the F159 (MTRN) instruction is used to send and receive data.
When data has been sent from FP
Σ
via the RS485 communication of AFPG806, start sending data to
FP
Σ
side after the time mentioned below passed at the receiver.
In case of 19200 bit/s: 1 ms In case of 115200 bit/s: 200µs

Note1) The communication format and baud rate should be set to match the connected devices.
Note2) The RS485 port of the AFPG806 is either 19200 bps or 115200 bps only.
Also the baud rate (communication speed) must be identically set by the system register and the
dip switch in the communication cassette.
Reference:
<7.1.4 Setting of AFPG806 Switch>
Note3) Connect the “
−
“ terminal and the “E” terminal with a lead wire to make the termination resistance
of the AFPG803 effective.
The termination resistance of the AFPG806 is specified by the dip switch located in the
communication cassette.
