Temperature Rise Judgment Function

This function judges whether the temperature process value (PV) is within the temperature rise completion range.
Setting method
Configure the settings as described below.
■Temperature rise completion range setting
Specify the width of the temperature rise completion range for the set value (SV).

External (Other Analog Module) I/O Function

This function enables inputs and outputs using another analog module on the system.
Input
The temperature control module generally uses the temperature processed by the thermocouple or platinum resistance
thermometer connected to the module as the temperature process value (PV). The temperature control module can use the
digital input value of the current or voltage converted in another analog module on the system as a temperature process value
(PV).
■Setting method
Store the value of another analog module in 'CH1 Temperature process value (PV) for input with another (external) analog
module' (Un\G438).
Select the control mode to use the external inputs using control mode switching.
• If a greater value than (external input range upper limit + 5% of external input range) is set, an input upper
limit alert occurs, and an event (Un\G429, b0) turns ON.
• If a smaller value than (external input range lower limit + -5% of external input range) is set, an input lower
limit alert occurs, and an event (Un\G429, b1) turns ON.
