abSl_cfg[16]
/ Slave configuration area
This variable is a field of 16 bytes and shows whether or not a certain slave station has been
configured on the network. There is 1 bit for each slave. If set, the slave address has been
configured. The following table shows the bit related to its slave address:

If the abSl_cfg bit of the corresponding slave is logically:
'1' - The slave is configured in the master, and serviced in its states.
'0' - The slave is not configured in the master.
abSl_state[16]
/ Slave state information area
This variable is a field of 16 bytes and contains the state of each slave station. There is 1 bit
for each slave. If set, the slave is present on the network. The following table shows the bit
related to its slave station address:

If the abSl_state bit of the corresponding slave station is logically:
'1' - The slave and the master are exchanging their I/O data.
'0' - The slave and the master are not exchanging their I/O data.
