I am reading the ai value of moxa E1242 multifunctional IO module and I have a problem, Cannot display floating point numbers, only integer numbers, cannot display decimal places. What's the reason? thanks. #moxa1242.cmd #!./../../bin/linux-x86_64/modbusApp < envPaths dbLoadDatabase("../../dbd/modbus.dbd") modbus_registerRecordDeviceDriver(pdbbase) drvAsynIPPortConfigure("moxa","192.168.127.254:502",0,0,1) asynSetOption("moxa",0, "disconnectOnReadTimeout", "Y") modbusInterposeConfig("moxa",0,5000,0) #read moxa E1242 AI_scaledValue,7 is little endian,8 is big endian drvModbusAsynConfigure("MOXA_E1242_In_Word", "moxa", 255, 4, 0x208, 0x8, 0x7, 2000, "moxa E1242") # Enable ASYN_TRACEIO_HEX on octet server asynSetTraceIOMask("moxa",0,4) # Enable ASYN_TRACE_ERROR and ASYN_TRACEIO_DRIVER on octet server asynSetTraceMask("moxa",0,9) dbLoadTemplate("moxa1242.substitutions") iocInit asynReport 1 dbl #moxa1242.substitutions #asyn record for the underlying asyn octet port file "$(ASYN)/db/asynRecord.db" { pattern {P, R, PORT, ADDR, IMAX, OMAX} {MOXA: OctetAsyn, moxa, 0, 80, 80} } file "../../db/ai.template" { pattern {P, R, PORT, OFFSET, BITS, EGUL, EGUF, PREC, SCAN} {MOXA:, ADC1, MOXA_E1242_In_Word, 0, 16, 0., 65535., 3, "I/O Intr"} {MOXA:, ADC2, MOXA_E1242_In_Word, 1, 16, 0., 65535., 3, "I/O Intr"} } #ai.template record(ai, "$(P)$(R)_AI") { field(DTYP,"asynInt32") field(INP,"@asynMask($(PORT) $(OFFSET) $(BITS))MODBUS_DATA") field(LINR,"LINEAR") # field(LINR,"NO CONVERSION") field(EGUL,"$(EGUL)") field(EGUF,"$(EGUF)") field(HOPR,"$(EGUF)") field(LOPR,"$(EGUL)") field(PREC,"$(PREC)") field(SCAN,"$(SCAN)") } #traceIO 2021/11/17 15:41:17.075 192.168.127.254:502 write 12 01 17 00 00 00 06 ff 04 02 08 00 08 2021/11/17 15:41:17.083 192.168.127.254:502 read 25 01 17 00 00 00 13 ff 04 10 13 b0 40 f0 00 00 00 00 00 dc 3b 5c 00 a0 3b a0 #caget display [gaozh@localhost db]$ caget MOXA:ADC1_AI MOXA:ADC1_AI 7 note:The actual input is 7.5V. application environment: EPICS 7.0.3 Asyn R4-33 Modbus R2-11 Thanks, Gao Zhenhua --- BSRF(Beijing Synchrotron Radiation Facility) Email:gaozh at ihep.ac.cn
