SYNRAD FH Series Flyer Operator’s Manual Version 3.4
Conguration
Keyword: Error
Operation: Continuous, strobed
Required: No
Format: “Error=arg1 arg2” where the arguments consist of decimal or hexadecimal values.
Argument: Arg1 is a mask that denes the output bits to set or clear. Arg2 is the desired out-
put state.
Notes: Error denes the output state that is set on an error condition just prior to the
mark session ending. If the Error keyword is not dened in the Master Control
File, Flyer ends the mark session with outputs remaining in their current state.
Error conditions include: a corrupt Master Control File, an invalid mark le, or a
nonexistent mark le—likely due to an incorrect path or lename specication.
Example: # specify outputs OUT5 and OUT4 as the mask. OUT5 = 32 and OUT4 = 16,
# so mask value is 48 decimal or 0x30 hex.
# The desired output state on an error is OUT5 = 1 and OUT4 = 1, so the
# output value is 48 decimal or 0x30 hex.
Error =0x30 0x30
# remember that a space is a data delimiter!
# next step in Master Control File.
Continuous MCF example
# Continuous Master Control File example.
# A new le (or the same le) is loaded into Flyer memory for each mark.
# Each mark begins and ends a distinct mark session.
# OnBeforeMarkSession and OnAfterMarkSession events occur before/after each mark.
Type=0
# the Strobe keyword is not required for continuous operation.
# Set output OUT7 to “1” and OUT6 to “0” to indicate that another input read/le match
# operation will begin after the InitialDelay command.
SetDigitalInit=0xC0 0x80
# Add a 5-millisecond (ms) delay to allow input states to transition and settle before read.
InitialDelay=5
# Add a NullFile command – if input states do not match a valid le, then wait 10 ms
# and check inputs again.
NullFile=10
# Add Error command keyword to set output state before mark session ends if
# error condition occurs. Set OUT7 to “0” and OUT6 to “1” on error.
