SP Number Set
Select when registering to the contact input for switching the SP number.
SP No. Selection Source
When specifying input contacts of SP No. settings, select the loop number of the SP
Number set to be switched. Activate or deactivate each loop number (CX1000: LOOP1
and LOOP2, CX2000: LOOP1 to LOOP6 (up to 4 loops if 4LOOP was selected under 6/4
Loop selection)).
Pattern Number Selection (When Program Control for Internal Loop is ON)
(When [Program Control] for [Internal Loop] is ON)
With program control, you can select the range of pattern numbers when switching
program patterns through contact input. The pattern numbers are entered in binary
according to the number of relays required as shown in the following chart.
Pattern No. No. of Relays Assigned Relay(s)
1 1 (1 bit) DI001
1–3 2 (2 bits) DI001, DI002
1–7 3 (3 bits) DI001–DI003
1–15 4 (4 bits) DI001–DI004
1–30 5 (5 bits) DI001–DI005
These are automatically registered under contact inputs according to the selected range
of program pattern numbers. [1–15] and [1–30] are active only if the number of program
patterns is 30 (/PG2).
Control Input Channel (When PV/SP Computation Is ON, and with CX Style
Number S3 or Later)
When PV/SP computation is ON (see Control Action), set burnout and RJC (when PV/SP
computation is OFF, set in “Internal Loops”).
Burnout
Turn each control input channel ON or OFF.
RJC (Type, Volt (uV))
This is the reference junction compensation setting for thermocouple inputs. Set for each
control input channel. This setting is invalid on the CX main unit for PV input other than
thermocouples.
You can select [Internal] or [External] for Type.
If you select [External], set a voltage in the range from -20000 uV to 20000 uV.
