Controlinc 1746-C (Version 5.21) Network Master Users Guide (2004-11-18)
5.3.4.2. Table [0] … The Configuration Values (RSLOGIX-500).
In this example, the memory areas:
N10:0 N10:63: Indicates the 64-word table the PLC sends to the 1746-C.
N11:0 N11:63: Indicates the 64-word table the 1746-C sends back to the PLC.
Interesting & Important Note in this example:
In this example, the configuration the PLC would like to have (N10:0
N10:16) does NOT
agree with the configuration information the 1746-C actually has and is being read back (N11:0
N11:16). Also notice the configuration values being reflected back by the 1746-C … they
are all factory default values.
This screen reflects a state in which the PLC has not sent a “write table [0]” command to the
1746-C to set configuration values. Therefore, this 1746-C is currently running and “thinking”
that
There are 60 actuators on the network.
The scan period should be 50 scans long
However, the PLC actually “wants”
48 actuators on the network.
A scan period 10 scans long
To remedy this disparity of operation … the PLC needs to send the “write table [0]” command to
the 1746-C to set configuration values (word [1] =/= 0).
