Subject: Base R7.0.2.2 VME_IO Parsing

Hello All,

 

I have discovered during the upgrade process from Base v3.14.x to v7 (specifically 7.0.2.2) that certain support modules do not work correctly.

 

I am experiencing issues with the parsing of VME_IO INP/OUT specifications (“#Cn Sn @parameter” format) during dbLoadRecords.

 

For example, the mrfioc2 support module defines a record as:

 

record(bo, "CLA-C16-TIM-EVG-01:ResetMxc-Cmd") {

    field( DTYP, "EVG")

    field( DESC, "EVG Reset MXC")

    field( OUT,  "#C S @EVG-01")

    field( PINI, "YES")

    field( VAL, "1")

    field( UDF, "0")

}

 

The OUT field of this record is acceptable to 3.14.12.5 but 7.0.2.2 kicks this out on dbLoadRecords due to the missing card and signal numbers.  A v7 ‘fix’ to this is to replace all “#C S” instances with “#C0 S0”.

 

Another support module defines a record as:

 

record(ao,"CLA-C16-IOC-CS-01:CENTRAL-SMONCONF40")

{

    field(DESC, "sys_mon config")

    field(DTYP, "ifc1210")

    field(OUT , "#C S0x40 @SMON")

    field(VAL , "0")

    field(PINI, "YES")

    field(PRIO, "LOW")

    field(FLNK, "CLA-C16-IOC-CS-01:CENTRAL-CORETEMP")

}

 

Again, this is acceptable to 3.14.12.5 but 7.0.2.2 kicks this out on dbLoadRecords due to the use of a hexadecimal format signal identifier.  A v7 ‘fix’ is to replace all hex specifiers with decimal.

 

Is this behaviour an intentional change from Base 3.14->7 ?  Or am I missing something here?

 

Thanks,

 

Graham
