Can I communicate from a SLC processor to the HI 6500 over EIP?

Yes, you can communicate with the SLC to the HI 6500 over the EIP connection. 

Find attached a copy of simple code to read/write to the HI 6500 EIP unit. Recognize the Target address to use for the read (N7:0) and write (N11:0).  NOTE:  These address are within the unit and are not associated with the same named registers within the SLC.

The length of the tables is 24 16 bit registers so the data tags used for the reads and writes should be set to this length.  

The table registers are defined as:

Output Table:
Command - command being sent to the unit.
Command Aux data - if additional data needed for command.
Parameter ID - ID number of parameter to read/write.
Parameter Value - new value to write to selected parameter.
Reserved
Reserved
Reserved
Parameter RD1 ID - parameter ID to read in this location.
Parameter RD2 ID - parameter ID to read in this location.
Parameter RD3 ID - parameter ID to read in this location.
Parameter RD4 ID - parameter ID to read in this location.
Parameter RD5 ID - parameter ID to read in this location.

Input Table:
Command Echo - echo of command sent to unit.
Command Status - status return for the command sent.
Parameter ID - echo of parameter ID
Parameter Value - value of parameter specified.
Instrument Status - status word of the instrument
Net Weight
Gross Weight
Parameter RD1 value - value of parameter specified in output table Parameter RD1 ID
Parameter RD2 value - value of parameter specified in output table Parameter RD2 ID
Parameter RD3 value - value of parameter specified in output table Parameter RD3 ID
Parameter RD4 value - value of parameter specified in output table Parameter RD4 ID
Parameter RD5 value - value of parameter specified in output table Parameter RD5 ID

Parameter IDs and command numbers can be found in the HI 6500 users guide.

NOTE:  The weight values, including parameter values in weight units (like motion tolerance) will be in floating point format.  These values may need to be converted or copied into REAL registers to be read properly.  Also, the SLC processors expect the order of the registers to be swapped so you may need to re order the data within the registers to allow the copying so it reads correctly.
