The display is refreshed each scanning cycle.
The drawings of the LEDS on the left side indicate the status of
communication with each of the RF SLAVES (or with each RTU). An RTU,
which responds properly, will be indicated by a LED lighting constantly. An
RTU that did not respond the call of the MASTER will be indicated by a
blinking LED. The RTUs that were not called by the MASTER either because
they are undefined or because the call of the MASTER was not received
remain dark.
On the right side of the window appear rows of characters that describe the
information transmitted either by the MASTER or by one of the SLAVES. The
rows are shifted downward with each new row received by the RF EAR.
The following r
ow contains information about the MASTER’s transmission :
00:01:05(852) M->X (04)02 00000000(00) TD AA RSSI=66
The response of the slave has the following format:
00:01:05(901) M<-X (04)02 00000010(02) NT OK RSSI=66
Notice that in the 8 bits string containing the status of the outputs or the inputs
the rightmost digit represents the lower Output/Input bit.
When an RTU is defined to communicate through a REPEATER, there will be
4 rows describing the process: 1) the call of the MASTER; 2) the transfer of
the call to the SLAVE by the REPEATER; 3) the response of the SLAVE and
4) the transfer of the response to the MASTER by the REPEATER.
