Communications Example
In this example, the E5ZE is operated with Memory Bank Designation Read
(RM) under the following conditions.
Unit no.:
1
Control Point:
3
Memory Bank no.: 2
Command
Response
3-21 Hysteresis Write: WH
Function
This command is used to set the hysteresis of control outputs of a control
point in ON/OFF operation.
1.
Hysteresis Write (WH) cannot be used at a control point being auto
-
tuned.
2.
Hysteresis Write (WH) is invalid if it is used for the E5ZE for 2
-
PID control.
3.
The hysteresis of the cooling
