measComp R4-2 available

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Folks,

 

R4-2 of the measComp module is now available.  This is from the release notes:

• Added support for the following new models:
• USB-SSR08, which supports 8 solid-state relays.
• USB-1808 and 1808X. These support 8 18-bit analog inputs, 2 16-bit analog outputs, 2 50 MHz pulse-generators, 4 digital I/O bits, 2 counter inputs, and 2 quadrature encoder inputs.
• Added support for counter device to E-DIO24.substitutions.
• Added OPI and iocBoot files for the USB-3104.
• drvUSBCTR.cpp and drvMultiFunction.cpp
• Added new parameters for modelName, modelNumber, firmwareVersion, ULVersion, driverVersion, pollSleepMS, pollTimeMS, lastErrorMessage
• replacedPulseGenWidth with pulseGenDutyCycle.
  pulseGenWidth is now calculated in the database from pulseGenFrequency and pulseGenDutyCycle.
• Changed the poller function to sleep for pollSleepMS rather than hardcoded time of 100 ms. The actual poller cycle time is now reported in pollTimeMS.
• drvMultiFunction.cpp
• Added a new global mutex to prevent multiple devices from calling the vendor library at the same time. This is needed to prevent errors with multiple Ethernet devices in the same IOC on Linux.
• Changes to support multiple pulse generators (timers) rather than only 1. Needed for USB-1808.
• Changes to support write-only and read-only digital I/O ports.
• The analog inputs are now read in the poller thread, rather than in the readInt32 method. The device support for analog inputs was changed from asynInt32 to asynInt32Average. This means that the device support now averages all of the values read by the poller thread between record processing. For example, if the poller thread is running at 100 Hz and the ai record SCAN field is .2 seconds then 20 values will be averaged each time the record processes. If the record SCAN field is I/O Intr then every value read in the poller thread will result in record processing with no averaging.
• measCompAnalogOut.template
• Changed PINI from YES to $(PINI=YES) so the default value can be overridden.
• Set PHAS=2 on the ao record to ensure that the Range record will process before the ao record.
• measCompBinaryIn.template
• Set DESC=$(DESC=) to allow optional passing a description macro value.
• measCompBinaryOut.template
• Set DESC=$(DESC=) to allow optional passing a description macro value on the bo and bi RBV records.
• Set PHAS=2 on the bo record to ensure that the Direction record will process before the bo record.
• measCompDevice.template
• New file with records for ModelName, ModelNumber, FirmwareVersion, ULVersion, DriverVersion, PollSleepMS, PollTimeMS, LastErrorMessage
• measCompEncoder.template
• New file with records for quadrature encoder inputs.
• measCompLongOut.template
• Changed PINI from YES to $(PINI=NO) so the default is now NO but can be overridden.
• measCompPulseGen.template
• Added DutyCycle record, and calc record logic to convert from DutyCycle to PulseWidth and vice versa.
• OPI files
• Add ModelName, ModelNumber, FirmwareVersion, ULVersion, DriverVersion, PollSleepMS, PollTimeMS, LastErrorMessage PV at top of each module screen.
• Documentation
• Added documentation for the records in the new measCompDevice.template file.
• Updated the screen shots to show the new measCompDevice embedded screen at the top.
• Added documentation for the USB-1808 models.
• Changed the analog input documentation to describe the new pollSleepMS record and asynInt32Average device support.
