Automation Professionals' Advanced Modbus Driver

Automation Professionals is pleased to announce a new production release of this module, with a number of bugfixes, and the new support for scripted device creation (as mentioned over here):

For Ignition v8.1+: v1.1.11.250071612

Notable fixes:

  • File Register read/write framing errors for RTU connections.
  • Input/Holding/File Register corrupted word swapping for all 64-bit data types.
  • Missing parser entry for the "IBCD" data transform for IR, HR, and HR addresses.
  • Fixed stray errors (NPEs in particular) on device shutdown.
  • Fixed Server failure to recover from RTU over TCP channel failures by applying idle TCP timeout to them.

This version also includes BETA support for Extended Lufkin Address Mode ("ELAM"), which expands the range of unit addresses to 0-2295. This support is only in the client driver. The client driver does not use this protocol extension's large packet functionality.

Corresponding support for the Server driver type, excluding large packet functionality, is planned. (If only for my own QA purposes.)

All users should upgrade.
