Variable names in EPAM4 must be defined with a full name /<Driver>/<Host>/<Variable>.
The ARTI communication driver in EPAM3 was replaced by the so-called PLCH (in DRVparam). The PLC handler supports communication to Codesys V2.3 and V3 controllers. The hosts (communication channels) are configured in the same way as with EPAM3.
All variable names must then be adapted as follows:
| 1. | Delete Table UserVar |
| 2. | Replace <Host>/ , or /ARTI/<Host>/ with /PLCH/<Host>/ (entire workbook) |
| 3. | Execute Build |
The RTS reports errors in the resolution of variable names with Runtime Error
