Content | CP 242-8 as AS-Interface Master 3-9 CP 242-8AS-Interface Master / PROFIBUS DP Slave – Release 01 C79000–G8976–C109/01 3.5Command interface of the CP 242-8 Meaning You require the AS-i command interface when you want to use functions over and above pure I/O data exchange with the AS-i slaves (for example assigning parameters to slaves from within the S7-200 program, modifying slave addresses etc.). Command Buffer and Response Buffer Command calls are made to the CP 242-8 from within the user program. You specify the command call in a command buffer and start the job. The command buffer is in the analog output area of the CP 242-8 (for example starting at AQW0 if the CP 242-8 is plugged in directly beside the S7-200 CPU). Depending on the command to be executed (see Section 3.6), the response data occupy banks 2 to 5 in the analog output area of the CP 242-8. On completion of the job, the job status and any response data are made available in a response buffer. The response buffer is in the analog input area of the CP 242-8 (for example starting at AIW0, if the CP 242-8 is plugged in directly beside an S7-200 CPU). Depending on the command that was executed, the response data occupy banks 2 to 5 in the analog input area of the CP 242-8. Requirements Remember that the following requirements must be met before a command call is sent from within the user program: The PLC_RUN bit must be set to “1” in the control byte of the CP 242-8. By setting the CP_READY bit in the status byte to “1”, the CP 242-8 signals that it is ready after turning on the power. Note If CP_READY is set to 0, no AS-i program execution is possible. |
