MSTR Type 5 Write Global Data

This command is used in a host processor to ‘publish’ Global Data which all slaves on the Modbus Plus highway may access. The 1560-MBP units can be configured to read the Control and Reference values from this Global Data table.

2.1.2 Modbus Register Map

A pre-defined register map has been provided in the 1560- MBP unit. This map is detailed in Appendix A, and shown below. The full memory map is dependent on the A-B device which is connected to the 1560-MBP unit.

On power-up, the 1560-MBP unit polls the remote device and determines the maximum number of parameters that exist in the SCANport device. If the number is greater than 2000 the parameter list is limited to 2000.

(1)Note that 40001 and 40002 are only accessible with MSTR Type 1 if ‘Global Control’ is disabled in the 1560-MBP.

(2)Represents Control and Reference Words which are controlled by host when ‘Global Control’ is enabled.

(3)Words 40011 up to 40020 are ‘Published’ by 1560-MBP in the mode Global Data space. A host can access these values using a MSTR Type 6 instruction or Peer Cop (see Appendix C), or an MSTR Type 2 data read.
