DIGITAL PID CONTROLLER
(4) Sync-Master/Slave Communication set
Master controller can be set only one and others should be set as Slave. In Sync
communication, no need to set Address and communication option. When set in Slave (Syns),
it works RBS menu.
(3) Modbus communication setting
① Modbus-ASCII
COM.P : MODA, BPS : 9600, PRTY : EVEN, STOP : 1-BT(bit), DTLN : 7-BT(bit)
② Modbus-RTU
COM.P : MODB, BPS : 9600, PRTY : EVEN, STOP : 1-BT(bit), DTLN : 8-BT(bit)
(2) Modbus protocol and T50 series
The Modbus communication protocol function code in the T50 series is comprised of a
function code that reads and writes D-REGISTER, and another that searches for Loop-
Back. For more information, please refer to the separately distributed Temcoline protocol, or
contact us by our website or our customer service center.

Description
The Modbus support device uses as address #400001~400999 in the 16-bit holding
register range, which includes 400001~465536.
When using a touchscreen for interface, the read/write addresses must be set at 400001
(D-Reg. 000) ~ 400700 (D-Reg. 699) for Pro-Face products.
For EasyView products, the device setting must be at 4x (16-bit), and the address at 001
(D-Reg. 000) ~ 700 (D-Reg. 699).
In Modbus communication, the address will be designated as the real
communication frame address +1. This is because the user may choose
addresses from #400001 onward. (Example: #400001 = D-Reg. 000)
① Communication line wire suggested
to use twisted pair shield wire.
② Termination resister must be
connected two pieces(120Ω 1/4W)
only at both ends.
