When the Master first suspends polling of a particular slave, it creates an Error
Delay Counter for this slave address and set the value in that counter equal to
the Error Delay Counter parameter in the configuration file. Then, each time a
command in the list is scanned that has the address of a suspended slave, the
delay counter value for that slave will be decremented. When the value reaches
zero, the slave state will be set to 1. This will re-enable polling of the slave.
The first word in the defined register locations contains the status code for slave
node address 1. Each successive word in the list is associated with the next
node in sequence, up to slave node address 255.
Note:
The values in the slave List Status tables are initialized to zero (0) at power-up, cold boot
and during warm boot.
