9.2 Modbus - Supported Functions
1)
Registers ranges 8000 and 9000 are Daniel long word or oating point registers.
To calculate the related Modicon registers use the following table:
Daniel Modicon Data type
8001 - 8499 equals 5001 - 5999 long word
9001 - 9999 equals 6001 - 7999 oating point
or the following pages for comparisons of all Daniel and Modicon registers.
9.3 List Of Parameters And Registers - Sorted By Tag Name
Note!
The client access column in the following list provides information about the read only (RO) or
read/write (R/W) access of each parameter.
All parameters with read/write access and tag names beginning with "Service." require entering
the service level access code into the register 3008 for parameter "Service.RemoteSecurity" to
enable write access.
