Mewtocol-7 Com
Getting the status of the plc
%EE#RT
Normal plc would return the default, see above.
The FP7 series returns:
%EE$RT0000000100000000
This indicates that the device uses the Mewtocol 7 format
When trying to use EXRT the FP7 returns not supported
[R] %EE#EX00RT00
[S] %EE!42
Then request the status from the PLC using Mewtocol 7
[R] >@EEE00#30STRD00
[O] >@EEE00$30STRD
