These controller tags are a 'scratchpad' area of intermediate data storage
variables used by the ladder logic to keep track of various logic processing
functions.
Controller Tag Description
WarmBoot Setting this tag to 1 will cause the module to reload, refreshing
configuration parameters that must be set on program initialization.
Only use this command if you must cause the module to re-boot.
ColdBoot Set this tag to 1 when the module is required to perform the cold
boot (hardware reset) operation. Do this when the module is
experiencing a hardware problem requiring a hardware reset.
BPLastRead This tag stores the latest Read Block ID received from the module.
This value changes frequently.
