    40XXX registers are identical to the data that was present in the DGC-500 and DGC-1000 products. This allows the DGC-2020 to work seamlessly in Modbus applications where it is replacing a DGC-500 or DGC-1000. The 42XXX registers contain all information included in the DGC-2020 and should be used for any new Modbus applications.

    DETAILED DGC-2020 MESSAGE DEFINITION Device Address The DGC-2020 Device Address can be any value in the Modbus protocol Device Address range (1 - 247). A query with a Device Address of 0 signifies a Broadcast message to all slaves - the connected DGC- 2020s will not respond to the broadcast query.
  • Page 219 • Function 08, Subfunction 00 - Diagnostics: Return Query Data • Function 16 - Preset Multiple Registers, Non-Broadcast & Broadcast The only Broadcast query supported by the DGC-2020 is the Preset Multiple Registers query. Read Holding Registers Read Holding Registers - General QUERY: This query message requests a register or block of registers to be read.
  • Page 220 • There are several instances of registers that are grouped together (signified as DP or TP) to collectively represent a single numerical (vs. ASCII string) DGC-2020 parameter value. A query to write a subset of such a register group will result in an error response with Exception Code “Illegal Data Address”.

    This field contains a 2-byte CRC value for transmission error detection. The master first calculates the CRC and appends it to the query message. The DGC-2020 recalculates the CRC value for the received query and performs a comparison to the query CRC value to determine if a transmission error has occurred.
