• If the BASIC Unit does not operate at all, contact your OMRON representative.
The following errors may occur if the unit number is set incorrectly or if the
memory switches cannot be read or written correctly. The BASIC program can-
not be executed if any of these errors occur.
The error codes will be indicated as a binary value on the user indicators 0
through 7, with each indicating a binary digit between 2
turns ON to indicate a 1 in the 1's digit, indicator 1 turns ON to indicate a 1 in the
2's digit, indicator 2 turns ON to indicate a 1 in the 4's digit, etc.
Problem
The same unit number has been set for two
CPU Bus Units.
The unit number is already used for another
Unit.
Unit is not registered in I/O table.
Unit number is not read correctly from CPU
Unit.
Cyclic interface operation error.
Error occurs while reading or writing the CPU
Unit's memory switches.
BASIC Unit will operate with default memory
switch values.
• Before replacing the Unit, be sure to turn off the power.
• After replacing the Unit with a new one, check again to see if the old Unit is
really defective.
• When sending a defective Unit to OMRON for repair, describe the symptoms of
the error as clearly as possible.
• When the BASIC Unit malfunctions, the program in the internal RAM or EE-
PROM of the BASIC Unit cannot be read at all. It is therefore recommended
that the program be saved to a memory card of the CPU Unit or to a floppy disk.
For details, refer to Section 4-4 Program Save and Load.
• For quick recovery in case of trouble, always have at least one spare Unit avail-
able.
The maximum life of the battery is 5 years, regardless of whether or not power is
supplied to the Unit.
The battery life when power is not supplied to the Unit varies significantly with
ambient temperature. The higher the temperature, the shorter the life of the bat-
tery.
