Control section and starting word of the control file. (The control file is
usually a binary file; and, binary files must start at word 0.)
Channel always the address E2.14.1 where: E2 is the module status area
of PLC3 memory; 14 is the section number of the memory
communication module; and, 1 is the number of the memory
communication module
<command> one of the function commands for controlling memory
communication module operation.
Important: You may enter either the entire name or the abbreviated name
as listed in Table 4.G.
In the remainder of this section, we describe the operation of each
command. Some functions require one or more parameters following the
command. Parameters you have to enter, we enclose in angle brackets
(< >).

Stop
Command
The STOP command lets you discontinue continuous data table transfers,
continuous file transfers, or both. The STOP function is equivalent to the
INACTIVE function in LIST.
After the primary processor executes a message instruction containing the
STOP command, the memory communication module stops transferring
data tables, files, or both from the primary to the backup processor. If you
execute this command while a data or file transfer is active, the current
transfer will be allowed to complete before the stop function becomes
effective. Then, all subsequent data table and file transfers will be
inhibited.
