9.2 Config File Master Section
This section is required only for the master task. It defines the master’s poll loop settings,
the list of slave machines with which the master communicates, and a series of polls to
perform. Six commands are supported, all of which are enclosed by brackets ([]):
[POLL DELAY <NNN>]
This specifies the delay between messages (polls). The value is in system
ticks (a tick is 1/60 of a second)
[LOOP DELAY <NNN>]
This specifies the delay at the end of the poll loop (i.e. the time between the
last message and starting the first message again). The value is in system
ticks (a tick is 1/60 of a second).
[RETRY LIMIT <NNN>]
This specifies the number of retries the master should perform for a single
message before classing it as failed. The retry counter is incremented
following a timeout (see below).
[TIMEOUT <NNN>]
This specifies the amount of time (in seconds) that the master waits for a
valid response from the slave before it increments the retry counter. During
this timeout period, the master attempts to poll the slave every 3 seconds.
For example, for a TIMEOUT period of 60, the master attempts to poll 20
times.
[SLAVES <A> <B> <C> <D>]
This command specifies a list of up to 10 slave addresses with which the
master task communicates.
[SLAVE STATUS OBJ <KPINTARR Number> <KPINTARR Field>]
This command specifies the KPINTARR and Field (stream number) used to
indicate the status of the link.
For each configured stream, the Modbus master task updates the KPINTARR
with:
