Service data (acyclic communication)

Independent to the process data the Modbus/TCP has access to all b maXX parameters.
The Modbus register 600 - 652 is used:
Modbus Name
register
600 F: Format
601 DS: Data set
602 FB: Function block
603 PNR: Parameter num-
ber
604 FBI: Instance / Index of
the function block
605 Index 0
606 Index 1
607 Index 2
608 Index 3
609 Axis
610 Length
611 – Data
650
651 – Error code service data
652 access
Register 600 - 609 contains which parameter is read or written to.
Register 611 - 650 contains the data of the parameters of register 600 - 609.
Register 610 contains the data length (bit length) of the parameter access. The length
must be equal to the length of the selected b maXX parameter. Following lengths are per-
mitted: 1, 2, 4, 8 and 80 Byte
The data access of the selected parameter is possible via register 611 - 650.
