CIP Serial Driver Parameters
Parameter Options
Baud rate Toggles between the communication rate of 1200, 2400,
4800, 9600, 19200, and 38400.
Parity Specifies the parity setting for the serial port. Parity
provides additional message-packet error detection.
Select Even, Odd, or None.
Station Address The station address for the serial port on the DF1
master. The only valid address is 0...254.
DF1 Mode DF1 Full Duplex (read only)
Control Line No Handshake (read only)
Duplicate Packet Detects and eliminates duplicate responses to a
Detection message. Duplicate packets may be sent under noisy
communication conditions when the sender's retries are
not set to 0. Toggles between Enabled and Disabled.
Error Detection Toggles between CRC and BCC.
Embedded To use embedded responses, choose Enabled
Responses Unconditionally. If you want the controller to use
embedded responses only when it detects embedded
responses from another device, choose After One
Received.
If you are communicating with another Allen-Bradley
device, choose Enabled Unconditionally. Embedded
responses increase network traffic efficiency.
NAK Retries The number of times the controller will resend a
message packet because the processor received a NAK
response to the previous message packet transmission.
ENQ Retries The number of enquiries (ENQs) that you want the
controller to send after an ACK timeout occurs.
Transmit Retries Specifies the number of times a message is retried after
the first attempt before being declared undeliverable.
Enter a value from 0...127.
ACK Timeout Specifies the amount of time after a packet is
(x20 ms) transmitted that an ACK is expected.
