appropriate. ex: pulse-On, on-time=100, off-time=300, count=5 would give 5 positive

100 ms pulses, 300 ms apart.

There is a BLOCK input signal, which will disable the operation of the function, in the

same way the setting Operation: On/Off does. That means that, upon activation of the

BLOCK input, all 32 CMDBITxx outputs will be set to 0. The BLOCK acts like an

overriding, the function still receives data from the DNP3 master. Upon deactivation

of BLOCK, all the 32 CMDBITxx outputs will be set by the DNP3 master again,

momentarily. For AUTOBITS , the PSTO input determines the operator place. The

command can be written to the block while in "Remote". If PSTO is in "Local" then

no change is applied to the outputs.

For description of the DNP3 protocol implementation, refer to DNP3 communication

protocol manual.
