CIP SafetyOpen Type 2 Connection Frame Structure
The M580 standalone safety CPUs support CIP Safety connections created by SafetyOpen type 2 connection requests. The structure of the connection request frame is described below:
Parameter Name |
Description |
|
|---|---|---|
Connection Timeout Multiplier |
Used by the consumer of a connection to determine if any of the three standard connections should timeout. The timeout value for the connection is defined as: Connection RPI * (CTM+1) * 4 |
|
O_to_T RPI |
Originator to Target Requested Packet Interval. |
|
T_to_O RPI |
Target to Originator Requested Packet Interval. |

Target Node ID |
||
OUNID |
OUNID Date |
Originator unique Network Identifier: Identifies the originator in the SafetyOpen request. |
OUNID Time |
||
Originator Node ID |
||
Ping_Interval_EPI_Multiplier |
Defines the Ping_Count_Interval for the connection. |
|
Time_Coord_Msg_Min_Multiplier |
The minimum number of 128 μS increments it could take for a Time Coordination Message to travel from the consumer to the producer. |
|
Network_Time_Expectation_Multiplier |
The maximum age of safety data, measured in 128 μS increments, allowed by a consumer. |
|
Timeout_Multiplier |
The number of data production retries to include in the equation for unsuccessful connection detection. |
|
Max_Fault_Number |
The number of erroneous packets that can be dropped before the connection will be closed. |
|
Connection Parameters CRC (CPCRC) |
Connection Parameters CRC. A CRC-S32 of target connection parameters contained in the SafetyOpen type 2 request. |
