IP 265
10.3 Wiring Test
COM 265 provides a function for testing the electrical continuity between the IP 265's inputs/outputs
and the process I/Os' sensors or actuators of the process I/O.
There is no "wiring test" function as such. Instead, there is a special IP 265 utility called "WIRE",
which must be loaded into the IP when you want to perform a wiring test. The "On-line" function is
used to display the results of the wiring test.
The WIREPIP.S5D file is on the COM 265 installation floppy.
Preparations for the wiring test
Select the "WIRE" test.
There are two ways of "Selecting" the "WIRE" utility:
1. Press <F2> "Wiring" in the "Test" form and confirm with <
"WIRE" is then automatically displayed in COM 265's "Defaults" form.
2. Enter the program name "WIRE" in the "Defaults" form.
Load the "WIRE" utility into the IP 265 and set the IP 265 to RUN mode via the "Load IP 265"
service function.
Start the wiring test. Invoke the "On-line" test function ( Section 10.2).
The following are displayed in table form and updated cyclically:
• IP 265 24 V inputs
• IP 265 24 V outputs
• IP 265 5 V differential inputs
Note
The "WIRE" program does not have to be compiled.
Note
If you load the "WIRE" program into the IP 265 via the I/O bus, remember that you will
also overwrite the IP 265's EEPROM memory submodule, if one is plugged in.
