WRITE ANALOG WATCHDOG BANK 21
PURPOSE:
Writes to a bank of eight analog watchdog registers.
COMMAND TYPE:
Analog
PARAMETERS:
COMMAND Contains the value 21.
ADDRESS Contains the address of the Pamux brain board.
POSITION Contains the bank number.
VALUE ARRAY Contains the values to be written to each watchdog register in the bank. Each
element of this array corresponds to the watchdog register of one module
position within the bank. Element 0 corresponds to the first module position’s
watchdog register, element 7 corresponds to the last module position’s
watchdog register.
REMARKS:
When a watchdog timeout occurs, the values in the watchdog registers are written to their
corresponding output module positions. This task is performed automatically by the analog Pamux
brain board if a watchdog time has been previously set with the Set Analog Watchdog Timeout
command.
Only I/O points configured as outputs are affected.
EXAMPLE:
This example writes the value 1,024 to the watchdog registers of all module positions at address 10
of bank 1. The example assumes that these positions have been previously configured as outputs.
