Special features for graphic terminals:The address areas for fault bits ("PLC address of control words"+5) and acknowledgement can be divided to twostations:mm/nnMWgg,kkmm/nnMDgg,kkmm 1. station number 0...31nn 2. station number 0...31gg group number 0...31kk channel number 0...15"PLC address of control words" and "PLC address acknowledgement" are independent from each other; it dependson the system design whether they are both devices or not.The effect of such an address division is• the first half of the fault bits is read from station mm• the second half of the fault bits is read from station nn• the first half of the acknowledgement is read from station mm• the second half of the acknowledgement is read from station nnExample:PLC address of control words: 3/4MW10,0PLC address acknowledgement: 12/15MW5,0Number of fault words 31In this case the allocation is:Station 3 Station 4LEDsMW1,0...MW10,2 (3 words)Control words MW10,3...MW10,4 (2 words)Fault bits MW10,5...MW11,3 (15 words) MW 11,4...MW12,3 (16 words)Station 12 Station 15Acknowledgement MW5,0...MW5,14 (15 words) MW5,15...MW6,14 (16 words) The usual parenthesises of the AC31 addressing can now be cancelled for graphic terminals with protocoldriver Modbus-Master; splitted address area must be declared without parenthesisesExamples for valid addresses:11/12MW05,011/12MD5,102/3MW13,00 Only 10 characters are at the disposal!E98Process display and control/ Device Manual/ Issue: 07.01
