Explanation
1. The EMER instruction is applicable to CANOpen DS301 mode and Delta special mode.
2. Only the PLC firmware of V1.04.10 and later can support the instruction.
3. After receiving the Emergency message from the slave Node, the PLC will automatically store the data in the
specified storage device and set the Ok flag to ON.
4. It is recommended that the Node value should be specified from the slave node IDs which have already existed. If
the value is not one existing node ID or the slave has been disconnected, the PLC will not be able to receive any
message, set the Err flag to ON and show error code of communication timeout. (Refer to explanation of SR659
for error codes.)
