remote commands, and also can be placed in the MCC-545C schedule list
for periodic event application.
Command: EVENT, STATUS, {bit-name, or chan-name}
This form of the command lets the operator display an immediate value for
any discrete input bit or any ADC channel. For example: to display the
status on the DTR input line, EVENT,STATUS,DTR<cr>. To display forward
power, enter EVENT,STATUS,FPWR<cr>.
Command: EVENT, RESET, action
Define an action to be taken at power-up/reset. This is useful for setting
control outputs at a known state or sending a message to a host system
that the MCC-545C has been reset. These RESET actions will also occur if
the event monitor is stopped, then restarted. This allows entering new
RESET events into an existing table.
Command: EVENT, DIOHI, bit-name, settle, holdoff, action
Define an event that looks for a discrete input line to go to a high level.
Parameter Description
DIOHI
Scan discrete input signal for high condition.
bit-name
Name of discrete input signal to be scanned for high level. (single or multiple
inputs)
settle
Number of clock ticks for the input signal to settle at the high level before
declaring an event
holdoff
Number of clock ticks fo
r the analog input signal to settle at the low level to
be armed for detecting the next event.
action
MCC
-
545C action to be taken when event is declared. See actions below.
Logical combining of multiple discrete inputs is allowed. This is done by
expanding the bit-name parameter of the command into a list on inputs
separated by logic operator characters. For example, to test both the RTS
and DTR inputs in one event, use the string “,DTR & RTS,” in the bit-name
parameter. Up to 5 inputs can be used in a single event line. Any of the
inputs can be “inverted” before the combination. For example, if the DTR
input must be high and the RTS input low to trigger an event, use the string
“,DTR & !RTS,” in the bit-name parameter.
