8.4 Connection to a Temperature Controller
This section explains no-protocol communications with a Temperature Controller.
8.4.1 System Configuration
Temperature data is read by connecting a Temperature Controller (SR-Mini) manufactured
by RKC INSTRUMENT INC. to the RS-232C (Port 2) of the 217IF Module.
The engineering environment is provided by connecting the MPE720 Programming Device
to the 217IF (CN1).
No-protocol Communications Between the MP920 217IF and a
Temperature Controller Manufactured by RKC INSTRUMENT INC.
With this protocol, the SR-Mini temperature input values from CH0 to CH3 are stored in
MW07030 and later registers.
