Subject: | Modbus R2-6 available |

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. The release notes are here: http://cars.uchicago.edu/software/epics/modbusReleaseNotes.html The documentation is here: http://cars.uchicago.edu/software/epics/modbusDoc.html The tar file is here: http://cars.uchicago.edu/software/pub/modbusR2-6.tgz Cheers, Mark |
