Folks,

 

Release R2-6 of the EPICS "modbus" module is now available. This is from the release notes:

 

- Fixed a problem with function code 6 (write single register) on Wago devices when the MASK was not 0x0 or 0xFFFF.

  In this case a read/modify/write operation is required, and the driver was reading from the wrong address.

  On Wago devices the readback address for a register is offset by 0x200 from the write address.

  This offset was not being applied.

 

- Added 2 new records to statistics.template.

  $(P)$(R)HistTimeAxis is a waveform record that contains the X time axis for histogram plots,

  and MsPerBin is the time per histogram bin in msec.
