Cause
No communication protocol has
been set.
Communication protocol and
screen data type are mismatched
- The power was switched OFF
during screen data
initialization, checking, or
transmission.
- Transmission of screen data
was interrupted.
- Illegal data has been written to
the screen data memory.
No screen data is registered.
Allocated words have not been
set for the PT status control area
and PT status notify area.
The type of registered screen
data does not match that at the
PT.
No data is registered for either
the screen number set in the PT
status control area or the Initial
Screen set with the Support Tool.
Or the screen number that does
not exist are registered.
Section
Remedy
Using the memory switches, set the
communication method to be used for
communication with the host. (Refer to
Setting the Conditions for
Communications with the Host by Using
the Memory Switches in section 6 in the
Setup Manual.)
Initialize the screen data memory by
operation at the System Menu, then
re-transmit the screen data. (Refer to
Clearing Screen Data in section 6 in the
Setup Manual.)
If the problem persists, contact your
nearest OMRON representative.
Transmit screen data from the Support
Tool.
Allocate words for the PT status control
area and PT status notify area with the
Support Tool and then transmit the direct
connection information to the PT.
Initialize the screen data memory, then
transmit the correct screen data. (Refer
to Clearing Screen Data in section 6 in
the Setup Manual.)
Either specify a screen number for which
data is registered at the PT status control
area, or set the screen as the Initial
Screen in the System settings under PT
Configuration at the Support Tool.
