Hey Daniel; This answer is very clear; On TIa portal I have to work with micromaster and CPU 300 I'm going to make some tests with PPO1 (If I can't i'll do it with PPO3 :( ), how will it works to make the same process that you explain, cause this is what I see(Attachment) and don't understand much about that directions, there is a mix of them, some advices about PPO1?. And you say that the status can be read from PIW256 and PIW258. But do I have to send something before to read them or they are always present and always have the status value. Best regards

Hello Juan; DPWR_DAT and DPRD_DAT are absolutely required for the PKW are; these 4 words must be sent as a single telegram. DPWR_DAT and DPRD_DAT could be used for the PZD area, but I prefer simple Load/Transfer (Move) instructions for each word, it gives me a felling ofmore control. But this is a questoion of programming style. In the following FAQ, you will find sample programs fro Profibus control of a MM4 drive: 1 for L/T ocntrols of the PZD, one for the DPWR_DAT and DPRD_DAT odf the PZD,and 2 for the use of DPWR_DAT and DPRD_DAT with the PKW area. With these programs you can see how the different access to the controls is done, and choose your own prefered method. MICROMASTER 4 (MM4): Are there program examples for the Instruction Manual of the MICROMASTER PROFIBUS option module? Hope this helps, Daniel Chartier |
