Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with Micro Trend UTREND UTC Series. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: MICRO TREND UTREND UTC SERIES

Device Address
| Bit/Word | Device type | Format | Range | Memo |
|---|---|---|---|---|
| B | M_BIT | DDDDh | 10 ~ 2047f | *Note1 |
| DW | I | DDDD | 0 ~ 2047 | Float |
| DW | P | DDDDDD | 0 ~ 432143 | Float |
| DW | Q | DDDD | 0 ~ 2047 | Float |
| DW | M | DDDD | 1 ~ 2047 | Float |
| DW | R | DDDD | 0 ~ 1023 | Float |
| DW | I_INT | DDDD | 0 ~ 2047 | |
| DW | P_INT | DDDDDD | 0 ~ 432143 | |
| DW | Q_INT | DDDD | 0 ~ 2047 | |
| DW | M_INT | DDDD | 1 ~ 2047 | |
| DW | R_INT | DDDD | 0 ~ 1023 | |
| DW | I_ASCII | DDDD | 0 ~ 2047 | |
| DW | P_ASCII | DDDDDD | 0 ~ 432143 | |
| DW | Q_ASCII | DDDD | 0 ~ 2047 | |
| DW | M_ASCII | DDDD | 1 ~ 2047 | |
| DW | R_ASCII | DDDD | 0 ~ 1023 |
NOTE: *Note1: Use M_Bit to match the original software; you need to add 0 (INDEX 0) after the address.
E.g.:
M16 — for EBPro (EasyBuilder Pro) objects should be keyed as M160.
M2 — for EBPro (EasyBuilder Pro) objects should be keyed as M20.
