4.4 Restrictions
This section describes limitations and restrictions on the use of this
module.
The 115V AĆC/DĆC Input Module is a read only module. Attempts to
write to it will cause a bus error (severe system error). The following
are examples from programs that write to the module and should
therefore be avoided:
a. Referencing the module from a coil in a ladder logic task.
b. Referencing the module on the left side of an equal sign in a LET
statement in a control blockor BASIC task.
c. Referencing the module as an output in a control blockfunction.
