Parameter Description R/W
CH0 CH1
(1) +56 – Input CH0 Function
0: Input CH0
1: Difference input (Input CH0 - Input CH1)
2: Difference input (Input CH1 - Input CH0)
3: Addition input (Input CH0 + Input CH1)
R/W
(2)
– +133 Input CH1 Function
0: Input CH1
1: Difference input (Input CH0 - Input CH1)
2: Difference input (Input CH1 - Input CH0)
3: Addition input (Input CH0 + Input CH1)
R/W
+55 – External SP Input
0: Disabled
1: External SP input (4 to 20mA DC) (Note)
2: External SP input (0 to 20mA DC)
3: External SP input (1 to 5V DC)
4: External SP input (0 to 1V DC)
5: Cascade control (Note)
Note: When External SP input is selected in Input CH1
Function,
“1: External SP input (4 to 20mA DC)” is
selected as the default. When Cascade Control is
selected in Input CH1 Function,
“5: Cascade control” is
selected.
R/W
(3) +57 – Output CH0 Function
0: Output CH0
1: Output CH1
2: Both outputs (Output CH0, Output CH1)
R/W
(4) – +134 Output CH1 Function
0: Output CH1
(The selection of Output CH0 Function has priority.)
