Modbus Problems

[黄佳伟 via Tech-talk <tech-talk@aps.anl.gov>]

Hi，

    I meet some problems with modbus module.

   No errors and warnings when I execute the cmd file. However the 'STAT's of all pvs are 'UDF' when I execute "dbpr" in iocsh and if I caget these pvs, it shows "Channel connect timed out" and cannot fine the pv.

    Anyone knows what's wrong?

    Here is my `cmd` file:

 #!../synApps/support/modbus-R3-0/bin/linux-x86_64/modbusApp

dbLoadDatabase("../synApps/support/modbus-R3-0/dbd/modbus.dbd")

asynSetTraceIOMask("ChamberVaccum0", 0, 255)

asynSetTraceIOTruncateSize("ChamberVaccum0", 0, 512)

dbLoadTemplate("abb.substitutions")

iocInit

and here is my substitution file:

file "../synApps/support/modbus-R3-0/db/aiFloat64.template" {pattern

    {P,    R,              PORT,            OFFSET, LOPR, HOPR,   PREC, SCAN,       DATA_TYPE}

    {AC1:, Vac0,           ChamberVaccum0,  0,      0.,   10000., 11,   "I/O Intr", "MODBUS_DATA"}

    {AC1:, Vac1,           ChamberVaccum1,  0,      0.,   10000., 11,   "I/O Intr", "MODBUS_DATA"}

    # {AC1:, PrsAtGasCylinder, P04show,         0,      0.,   10000., 11,   "I/O Intr", "MODBUS_DATA"}

    {AC1:, PrsAtPumpTube,  P40show,         0,      0.,   10000., 11,   "I/O Intr", "MODBUS_DATA"}

}
