CIP Serial Driver Parameters
48
Parameter
Options
Default
Baud rate
Toggles between the communication rate of 1200, 2400,
4800, 9600, 19200, and 38400.
38400
Parity
Specifies the parity setting for the serial port. Parity
provides additional message-packet error detection.
Select Even, Odd, or None.
None
Station Address
The station address for the serial port on the DF1
master. The only valid address is 1.
1
DF1 Mode
DF1 Full Duplex (read only)
Configured as
full-duplex by
default.
Control Line
No Handshake (read only)
Configured as no
handshake by
default.
Duplicate Packet
Detection
Detects and eliminates duplicate responses to a
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.
Enabled
Error Detection
Toggles between CRC and BCC.
CRC
Embedded
Responses
To use embedded responses, choose Enabled
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.
After One
Received
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.
3
ENQ Retries
The number of enquiries (ENQs) that you want the
controller to send after an ACK timeout occurs.
3
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.
3
ACK Timeout
(x20 ms)
Specifies the amount of time after a packet is
transmitted that an ACK is expected.
