Parameter
Parameter type
Data type
Description
MSGTIME IN UInt
200
Specify how long to wait for the entire message to be
completely received once the first character has been
received. This parameter is only used when the message
timeout condition is selected. (0 to 65535 milliseconds)
CHARGAP IN UInt
12
Specify the number of bit times between characters. If the
number of bit times between characters exceeds the
specified value, then the end condition will be satisfied.
This is only used with the inter-character gap condition.
(0 to 65535 bit times up to 8 second maximum)
SEQ.CTL IN Byte
B#16#0
Sequence 1 ignore/compare control for each character:
These are the enabling bits for each character for the end
sequence. Character 1 is bit 0, character 2 is bit 1, …,
character 5 is bit 4. Disabling the bit associated with a
character means any character will match, in this
sequence position.
SEQ.STR IN Char[5]
0
Sequence 1 start characters (5 characters)
Table 12- 18 Condition codes
STATUS (W#16#....)

80C0 Illegal start condition selected
80C1
Illegal end condition selected, no end condition selected
80C2
Receive interrupt enabled and this is not possible.
80C3

Calculated length is enabled and length is not 1, 2 or 4.
80C6

80C7
Calculated length is enabled and calculated length is > 1024.
80C8
Response timeout is enabled and response timeout is zero.
80C9
Inter-character gap timeout is enabled and it is zero.
80CA
Idle line timeout is enabled and it is zero.
80CB
End sequence is enabled but all chars are "don't care".
80CC
Start sequence (any one of 4) is enabled but all characters are "don't care".
