Input/output (with Another Analog Module)
Function
This function can input and output with other analog modules (including A/D converter module and D/A converter module) on
the system.
Input
The temperature control module generally uses the temperature measured by the thermocouple or platinum resistance
thermometer connected to the module as the temperature process value (PV). The temperature control module can uses the
digital input value of the current or voltage converted in another analog module (such as A/D converter module) on the system
as a temperature process value (PV).
■Setting method
1.
Select one of "Input with Another Analog Module Measured Temperature Range (0 to 4000)" to "Input with Another
Analog Module Measured Temperature Range (0 to 32000)" in the following setting:
[Navigation window]  [Parameter]  Target module  [Application Setting]  [Control basic parameters]  [Input
range setting]
2.
Store the value of another analog module (such as an A/D converter module) in 'CH1 Temperature process value (PV)
for input with another analog module' (Un\G438).
• When the setting procedure 2 is executed without the setting procedure 1, an out of setting range error
(error code: 1950H) occurs.
• When this function is used, the value in 'CH1 Temperature process value (PV) for input with another analog
module' (Un\G438) is the target of the temperature process value (PV) scaling function. ( Page 68
Scaling Function)
Output
Instead of the transistor output from the temperature control module, an analog output value from another analog module
(such as a D/A converter module) can be used as the manipulated value (MV).
■Setting method
1.
Set the resolution of the manipulated value (MV) by the following procedure:
[Navigation window]  [Parameter]  Target module  [Application Setting]  [Resolution of the manipulated value for
output with another analog module]
2.
Store the value in 'CH1 Manipulated value (MV) for output with another analog module' (Un\G407) in the buffer memory
of another analog module (such as a D/A converter module).
• When the manipulated value (MV) is -5.0% to 0.0%, 0 is stored in Manipulated value (MV) for output with
another analog module. When the manipulated value (MV) is 100.0% to 105.0%, 4000, 12000, 16000,
20000, or 32000 is stored in Manipulated value (MV) for output with another analog module.
• The manipulated value (MV) (%) is stored into Manipulated value (MV) for output with another analog
module (digital output value) in real time.
