The ‘ArraySize’ field in the dialog determines the number of characters the string Tag can store. In this case 10 characters means
the HMI will access COMMSINTEGER(1), COMMSINTEGER(2) and the top 16 bits of COMMSINTEGER(3).
The table below illustrates some example strings (use of COMMSINTEGER has been assumed for this example):
CommsInteger (1) CommsInteger (2) CommsInteger (3) HMI String Display
0x41424344 (hex) 0 0 “ABCD”
0x41424344 (hex) 0x45460000 (hex) 0 “ABCDEF”
0x41424344 (hex) 0x45464748 (hex) 0 “ABCDEFGH”
0x41424344 (hex) 0x45464748 (hex) 0x494A0000 (hex) “ABCDEFGHIJ”
0x41424344 (hex) 0x45464748 (hex) 0x494A7691 (hex) “ABCDEFGHIJ”
0 0x45464748 (hex) 0x494A0000 (hex) “”
0x41424344 (hex) 0 0x494A0000 (hex) “ABCD”
0x41420044 (hex) 0x45464748 (hex) 0x494A0000 (hex) “AB”
You can see from the above table that the bottom 16 bits of CommsInteger(3) are not used. Also, as soon as a NULL (ASCII value
0) is encountered in the data the string is terminated, regardless of the contents of the remainder of the CommsInteger locations.
Mint Events

Mint Events
It is possible to associate Mint events / interrupts with Comms or NetData locations.
NextMove ES/ESB-2 only support the Comms array and will generate Mint Comms Events (1 to 5) whenever the HMI (or other
Modbus client) writes to one of the first five Comms locations. When using ES / ESB-2 the data does not have to change, whenever
a Comms location is written to the event is raised.
If using e100 products it is possible to utilise Comms events and / or Netdata events. Comms events (1 to 10) and NetData events
(0 to 31) are raised whenever the data in the associated location is changed. Writing the same value to one of these locations will
not raise an event in Mint.
If using e150 products it is only possible to utilise Netdata events. NetData events (0 to 31) are raised whenever the data in the
associated location is changed. Writing the same value to one of these locations will not raise an event in Mint.
