In addition to being able to set data on the HMI from a Baldor controller, the HMI panel can set its own
data, the nature of which is determined when the user designs their own HMI project using the HMI
Operator Panel design software.
The HMI communicates its own changes to the MintDrive using CAN event 12
(_setUNIOP_COMMS_UPDATE). This event will initiate the Mint CAN event handler (subroutine)
#CAN1
, and the associated CAN event information read using
CANEVENTINFO
will inform the user
which HMI comms location has changed. The
COMMS
keyword can then be used to read the new data if
required. Alternatively, the MintDrive can poll the comms data stored in the HMI to determine if it has
changed. The HMI allows the data to be stored in its databases in the following formats:
INT32_DB FLOAT_DB
Bit 1 bit Float 4 bytes - IEEE format
Byte 8 bits / 1 byte Float Inv. 4 bytes - IEEE format
Word 2 bytes
Word Inv. 2 bytes
Double Word 4 bytes
