Setting SLC Loop Number
Assign a unique SLC loop number to an LCM-320 by setting SW1 on the module to 1, 3, 5, 7, or 9.
The LEM-320 which is mounted behind this LCM-320 will be assigned the next-higher even
number. For example, if the LCM-320 is set to loop number 5, the LEM-320 mounted to it will be
set to loop number 6.
Enabling External Power Supervision
With LCM-320 revision 2.0 and higher, some type codes have external power supervision built into
the software; see Section 4.2 “Devices Requiring External Power Supervision” for details.
