Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with Altus ALNET-I. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Altus SeriesMode PO3042, PO3142, PO3242, PO3342, PL103, PL104, PL105, QK800, QK801, QK2000

| W | M | DDDD | 0 ~ 4096 | Memories |
| DW | D | DDDD | 0 ~ 4096 | Decimals |
| DW | F | DDDD | 0 ~ 1023 | Reals |
| DW | I | DDDD | 0 ~ 1023 | Integers |
| W | TM | HHHH | 0 ~ ffff* | Memory Tables |
| DW | TD | HHHH | 0 ~ ffff* | Decimal Tables |
| DW | TF | HHHH | 0 ~ ffff* | Real Tables |
