Description
Determines whether the Carrier Detect
signal of the serial port must be set for the
IEC station to receive messages.
Delay in milliseconds between activation
of the RTS signal and start of new trans-
mission.
Specifies maximum number of times that
a message is retransmitted after timeout.
Maximum waiting time in milliseconds of
a link layer response.
The connection is considered to be alive
if the delay between two consecutive
messages is shorter than the specified
time in milliseconds.
The type of data link connection used on
the channel.
Defines the delay after which the receiver
of channel is enabled after a message has
been issued.
The time that IEC link waits for the end of
the received message in seconds.
Specifies whether the handshaking mes-
sages (request, status of link, reset of
remote link) are restared when a 'request
status of link' message is received from
the remote end. When this is set to true
handshaking is restarted.
The number of characters for calculating
delay for resetting RTS signal.
