PLC polls input data sets
The following restrictions apply to this method:
The device index must be 1.
The variable to receive the data on the PLC must be:
– in the 40xxxx address range (for Schneider Modicon type PLCs)
– an array of 16 bit words
– long enough to contain the data set array(s)
All input data sets are transferred to the PLC in 16 bit word format with the first byte
placed in the least significant, or rightmost byte of the integer and the second byte
placed in the most significant, or leftmost byte of the integer.
FX0-GMOD as slave — Data addressing
The following table lists the address to read out the data sets.
Unit ID 1
Address (Base 1) Description Access Scope
[words]
1000 Request all enabled input data sets Get 16-101
10)
1100 Request input data set 1 data Get 25
1200 Request input data set 2 data Get 16
1300 Request input data set 3 data Get 30
1400 Request input data set 4 data Get 30
2000 Write all enabled output data sets data Set 5-25
11)
2100 Write output data set 1 data Set 5
2200 Write output data set 2 data Set 5
2300 Write output data set 3 data Set 5
2400 Write output data set 4 data Set 5
2500 Write output data set 5 data Set 5
All data sets can only be read or written as a block. It is not possible to read or write single
bits or bytes.
10)
Will correspond to all enabled input data sets.
11)
Must correspond to all enabled output data sets. Example: If only output data sets 1 and 2 are enabled, then
10 words (20 bytes) must be written. If all output data sets are enabled, then 25 words (50 bytes) must be
written.
