sending series of String or ascii from pc to plc
« on: April 02, 2002, 09:07:14 PM »
hi there,
I'm currently using mitsubishi fx1s-20dr plc. The problem that i m facing is sending a series of string or ascii to control the gate output to plc. I'm doing a mango project which consist of weighting and detect the size of mango. Then the computer will calculate the output channel for mango (varies from 1 to 8 since there are eight types of mango is using). I've manage to send the series of data to plc (ie. 4,3,2 & just a series of string) but the problem is that i do not how to write this in ladder format.For example if data 4 is sent then ladder format will have a function where it is waiting for the data input 4 then it calculate the delay time and the open the gate after the delay time.. Also if the data sent is 4,3,2 then the mango should be sent at output 4,3,2 at the same time(since 4 is coming first but time delay is different for each one).
many thanks
sun  :)

Dear sun919,

Please take note that this forum is meant for users or potential users of TRi brand of PLCs to raise their techical questions and not for Mitshubitshi PLC. Sending or receive ASCII string with M-series PLC is a piece of cake. But we are not sure how that is done in other brands of PLCs. To Using ladder program to do ASCII string processing is really using a wrong tool for the right job.  

You could post your questions at the General Discussion area and see if there are folks who are familiar with other brands of PLC. Good Luck.
