4. RS-485 MODBUS COMM.
P and S type are equipped with RS-485 communica-
tion terminal.
1) Terminal number is 485+ 485-.
2) Communication available at speed of 9600bps,
19200bps, 38400bps, 57600bps.
3) There is no terminating resistance within the
device. Thus, add a 150 terminating resis-
tance at the end after composing RS-485 line.
4) Monitoring all the measurement item and record-
ing elements of P/S type are available via com-
munication.
5) MODBUS communication map is put in a
separate manual. (Refer to P/S type MODBUS
map)
6) Various data of P, S type can be initialized
and reset, when the device is set at Remote.
Also, DO related control can be performed.
2. Profibus -DP COMM.
P and S type are equipped with RS-485 communica-
tion terminal.
1) Terminal number is 485+ 485-.
2) Possible to transmit data by installing Profibus-
DP module on the exterior, which is often used
in factor automation.
3) There is no terminating resistance within the
device. Thus, add a 150
terminating resis-
tance at the end after composing RS-485 line.
4) For details on Profibus-DP communication, refer
to Profibus-DP communication module manual.
