I'm using the DL-PC isa board to communicate with Allen/Bradley PLCs on
x86 hosted EPICS (R3.13.1).
I can successfully read and write integer files and can write the output
image table. I cannot read the input image table and cannot read nor write
a binary data table (e.g. B3).
Device support file version:
$Id: devAbDf1.c,v 1.7 1999/05/06 17:01:58 hill Exp $
Driver support file version:
$Id: drvAbDf1.c,v 1.8 1998/09/17 22:47:05 aptdvl Exp $
These records work:
record(bo, "$(user):boO_5") {
field(ZNAM, "OFF")
field(ONAM, "ON")
field(DESC, "Binary output")
field(DTYP, "AB DF1")
field(OUT, "@ /tyCo/1 1 O:0/5")
field(SCAN,"Passive")
}
record(ao, "$(user):aoN7_0") {
field(DTYP, "AB DF1 S")
field(OUT, "@ /tyCo/1 1 N7:0")
field(SCAN,"Passive")
}
record(ai, "$(user):aiN7_5") {
field(DTYP, "AB DF1 S")
field(INP, "@ /tyCo/1 1 N7:5")
field(SCAN,"I/O Intr")
}
These records do not:
record(bi, "$(user):biI_0") {
field(ZNAM, "OFF")
field(ONAM, "ON")
field(DESC, "Binary input")
field(DTYP, "AB DF1")
field(INP, "@ /tyCo/1 1 I:0/0")
field(SCAN,"I/O Intr")
}
record(bi, "$(user):biB3_0") {
field(ZNAM, "OFF")
field(ONAM, "ON")
field(DESC, "Binary input")
field(DTYP, "AB DF1")
field(INP, "@ /tyCo/1 1 B3:0/0")
field(SCAN,"I/O Intr")
}
record(bo, "$(user):boB3_1") {
field(ZNAM, "OFF")
field(ONAM, "ON")
field(DESC, "Binary output")
field(DTYP, "AB DF1")
field(OUT, "@ /tyCo/1 1 B3:0/1")
field(SCAN,"Passive")
}
Any ideas?
