CANopenDeviceSIL2 (FB) ¶ FUNCTION_BLOCK CANopenDeviceSIL2 EXTENDS CSB.CANopenSafetyBase This function block implements a CANopen Safety Slave SIL2 I/O driver which is realized through a black channel approach. It sits on top of an unsafe CANopen Slave Stack. Communication between both stacks is realized over shared memory. The function block can be enabled/disabled by S_xEnable . When S_xEnable gets TRUE the function block checks all conditions for safe communication each bus cycle: Unsafe stack is in OPERATIONAL state Configuration valid object (16#13FE) is set to 16#A5 Safety configuration signatures are correct Consistency of SRDO configuration data If a configuration error is detected (e.g. CRC mismatch) S_eError changes from NO_ERROR to the corresponding error code. If every condition is fulfilled the function block tries starting safe communication. Output S_xActive gets TRUE if all SRDOs are sent/received at least one time without any error. When communication error occurs (e.g. SCT/SRVT timeout, data mismatch, …), all SRDO communication is stopped: S_xActive = FALSE , S_eError <> NO_ERROR . Errors can be acknowledged by a rising edge of S_xErrorAck . Safe communication will be continued. Note Do not instantiate this function block. It will be instantiated implicitly. InOut: Scope Name Type Initial Comment Input S_xEnable BOOL TRUE TRUE : SRDO communication enabled; FALSE : SRDO communication stopped S_xErrorAck BOOL FALSE Pending error ( S_eError <> NO_ERROR ) can be acknowledged with rising edge. Output S_xActive BOOL FALSE TRUE : safe communication active; FALSE : safe communication inactive (in case of error or S_xEnable = FALSE ) S_eError CST.ERROR CST.ERROR.NO_ERROR Error code of pending error or NO_ERROR .
