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?
