The following table shows the causes of errors that may occur during CX-Pro-
cess Monitor Plus operations, and the action to take to clear the errors. Clear
the cause of the error using the table below.
Cause
No tag names have been registered in
the tag settings for Monitor Plus using
CX-Process Tool.
The computer communications type set-
ting in the System Monitor Builder
Screen is incorrect.
The Loop Control Unit's address in the
System Monitor Screen's node settings
and the actual Loop Control Unit's
address do not agree.
The Monitor Tag settings between CX-
Process Tool and CX-Process Monitor
Plus agree, but the Function Block data
when the Monitor Tag settings were
made using CX-Process Tool have not
been downloaded to the Loop Control
Unit.
Power supply to the PLC Unit is turned
OFF.
Communications cable is not con-
nected.
The tag number registered using CX-
Process Tool cannot be set correctly in
the CX-Process Monitor Plus.
If the communications type setting is not
CLK, the power supply to the PLC is
turned OFF, or the communications
cable is not connected.
FinsGateway Serial Unit initialization
failed. (i.e., network address set using
CX-Process Tool and FinsGateway
Serial Unit network address do not
agree.)
The actual Loop Control Unit in the Sys-
tem Monitor Builder Screen has not
been set using the System Monitor
Builder.
The network address when the Tag set-
tings were made using CX-Process
Tool, and the node address settings, do
not agree with the actual Unit.
A timeout occurred in communications
with the CPU Unit.
Action
Register the tag name using CX-Pro-
cess Tool, and then compile the tags for
Monitor Plus.
Change the communications type set-
ting.
Change the Loop Control Unit's address
in the node settings to agree with the
actual Loop Control Unit's address.
Download the Function Block from
when the Tags were set using CX-Pro-
cess Tool to the Loop Control Unit, and
restart the Loop Control Unit.
Turn ON the power supply to the PLC
Unit.
Connect the communications cable.
Reset the Tags using the Graphic
Builder Screen and the CRT Builder
Screen.
Turn ON the power supply to the PLC
Unit, or connect the communications
cable.
1. Make sure the network address set
using CX-Process Tool, and Fins-
Gateway Serial Unit network address
agree.
2. Compile the Monitor Tags, and then
reset the node PLC using the System
Monitor Builder Screen.
3. (If the above two actions fail)
Clear the Initialize Serial Port check box
using the System Monitor Builder
Screen.
Register the actual Loop Control Unit
using all the System Monitor Builders.
1. Make sure the network address and
node address set using CX-Process
tool, and the actual node address
agree.
2. Compile the monitor Tags using CX-
Process Tool, and then reset the node
PLC using the System Monitor Build-
er Screen.
Check to make sure that the PLC power
is turned ON.
Check to make sure that the FinsGate-
way settings are correct.
