The SLC Servo Module
Interface

The SLC Servo Module is a 12-word Input/Output specialty I/O
module. The module uses M files to download the module
configuration information. The module can also be configured to
enable the module interrupt capability available with the SLC
Backplane Interface.

Configuring the SLC Servo
Module

You configure the SLC Servo Module using M files that reside on the
SLC Servo Module. Refer to the SLC 500 Reference Manual (publication
1747-6.15), M0 and M1 data file section, for the M file interface and
addressing convention information. M files reside on the module and are
referenced by the ladder logic the same way as an integer file that resides on
the module. There are two M files (M0 and M1) associated with this and any
specialty module.

The SLC Servo Module only uses the M0 file that is used to transfer the
configuration information from the SLC Ladder to the SLC Servo
Module. Refer to Figure 7.1 for a functional block diagram of the data
flow.

The application program uses a copy file instruction to transfer the
data from a source integer or float file to the M0 file in the slot that
you want in the SLC Servo Module. A copy file instruction associated
with the M files works as an immediate output instruction. Therefore,
the normal ladder program execution stops when it encounters the
copy instruction with the M file. Ladder program execution does not
