9.6.5 "CP440 SLAVE" Program Example
In FB 40, RECV is called to query whether a job has been received from the master. For this
purpose, in the receive message frame the slave address is compared with its own address. As
soon as there is a job, the reply is sent to the master with the SEND call.
The parameters can be adapted for other slaves in OB 1.
