Before the 1775–KA module can transfer data to or from any file in
PLC–3 memory, that file must exist and it must have enough memory
allocated to it to accommodate the data transfer. You can create and
allocate a file using the PLC–3 memory management commands. Refer to
the PLC–3 Programming Manual (publication 1775–801) for a description
of memory management.
Table 5.B shows an example of editing a message procedure through an
Industrial Terminal connected to a 1775–S4A module. Table 5.C shows
how to edit the same message procedure through a data terminal
connected to a 1775–S4B module.
