Series 90 Micro Issues
1. There are few cases where you will not be able to establish Logic Equality with the Series 90 Micro PLC after storing or
loading. These issues relate to the fact that the Series 90 Micro calculates its own highest reference used rather than using
the value provided by VersaPro. You should also perform a “Check All” before storing the program to ensure equality
(CR71458, CR71694, CR72644).
a. Adding a %S7 Always On (ALW_ON) contact for some programs may be required in order to gain equality.
This occurs if the program uses function blocks connected directly to the power rail (i.e. without an interposing
contact). Since the Series 90 Micro does not allow function blocks to be directly connected to the power rail,
VersaPro inserts a hidden %S7 contact. If the program does not use a %S7 contact explicitly in the program, the
Series 90 Micro will not use the %S7 in the highest used reference calculation. However, VersaPro does use the %S7
in the highest used reference calculation.
Please note: The Series 90 Micro also requires VersaPro to insert a hidden ALW_ON contact after a timer
function which can also cause the same issue.
Resolution: In these cases including the case where you use a timer function, you should add a %S7 contact
somewhere in the program. This will allow the program to be stored and the status will show Logic Equal.
b. Using temporary variables can cause an equality issue with the Series 90 Micro. Create a Series 90 Micro folder
and connect to the PLC. Declare temporary variables: for the Boolean temporary variables use %Q or %M. Store
logic to the PLC. The store will be successful; however, “Logic Not Equal” will be displayed. Perform a verify of
logic. The verify results will be not equal. This is due to the recalculation of the Dec file by the Series 90 Micro PLC.
(CR72430)
Resolution: Use %T as the temporary Boolean memory area and the folder will be equal after storing to the Series 90
Micro PLC.
2. The IL language is not supported on the Series 90 Micro. If you attempt to convert the _MAIN block to IL, the
Information Window will display the message, “Series 90 Micro PLCs do not support IL.”
3. Invalid Program after import and modification of Series 90 Micro LM90 folder. A Logicmaster 90 Micro program
that contains a vertical wire immediately in front of a single coil will result in the error 0x05F2 - Invalid Program (or too
large for PLC) if it is imported into VersaPro, edited, and then stored to the Series 90 Micro PLC.
