Communications Example
In this example, the E5ZE is operated with Output Variable Limit Value Read
(RL) under the following conditions.
Unit no.:
1
Memory Bank no.: 2
Control Point:
3
Output Variable Lower
-
limit Value: 20.0%
Command
Response
4-15 Output Variable Change Rate Limit Value Write: WG
Function
This command is used to write control output variable change rate limit values
to a control point.
1.
Output Variable Change Rate Limit Value Write (WG) cannot be used at a
control point being auto
-
tuned.
2.
The output variable change rate limit function will not work at a control point
in the following cases.
• An output variable change rate limit value of 0000 is used for the E5ZE.
• The control point is being auto
-
tuned.
• The E5ZE is in manual operation.
00: Output variable lower-limit value
01: Output variable upper-limit value
02: Cooling-side output variable lower-limit value
for heating and cooling control model only.
03: Cooling-side output variable upper-limit value
for heating and cooling control model only.
