Hi, I' back after studying.... and several testing. Now I understand little bit the use of CX-Protocol, from the manual I try simple ladder using PMCR. So far all setting already done for scb but still not achive to get data from my weigh scale. I still cant understand how to write protocol of my weight scale into receive data on cx-protocol. Just trying from other ppl code and see what happen. Also cant understand what the trace result show. Still need much to learn. If anybody can guide me I really appreciate. I attached my cxp and also my weigh scale manual AD4402 (refer to 8.2 built in RS485 interface). also my cx -protocol file under this link, because I cannot upload psw file into this forum. http://www.box.net/shared/48kab2dhsg One question about terminator resistor. I set it on at SCB41-V1 but on the weigh scale no terminator resistor. Is it will effect the communication? AD4402.cxp ad4402.pdf

Hi, I am completely new about using Omron PLC. Now I'm working for a project using a weigh scale, the data from the weight scale I want to send to PLC using RS-485. My PLC is CS1G-H CPU43 and already have on board communication SCB41-V1 that have RS-485. Already go through the forum and found out that using CX-Protocol it can be done. Still reading the manual of CX-Protocol but too much to read made me confuse. My english is poor and take time to understand the manual. Can anybody make simple explanation how to do it the simplest way. For information my weigh scale can send ASCII code. Thank you.

Hi all... Thanks to Mr Chris and Mr Nibroc for the reply... I'ved check your reply long ago but unfortunately didn't have much time to reply back... Actually I've created my own program (my own way) by doing 2 times transfer (XFER)... using D1 to transfer new data to D2,D3 and so on... but my Japanese Programmer (actually Im not japanese) didn't really like my way because he said its to complicated(by the way I understand what he say), well maybe I'll have re-created again the program.... He had explain a little how he wanted the program to be like but I still can't get it right (Japanese Engineer stail of learning is do it yourself because its your own job and responsibility). Well that's that... wish me luck .... now I'm debugging my zx-t sensor to measure thickness.... and comes new problem .... well anyway thanks again for your help.... this is the best site ever

Thank you, I'm looking forwafd for your reply. Anyway if it's difficult maybe I just keep the data without transfering it. i also created block diagram gif file (sorry I misunderstand block diagram meaning before) to make it better. Thanks all.

Hi.... I've create acrobat file about my problem. Hope this will make it clear. And also thanks for giving your time. IndirectAddressing.pdf

Hi... firstly thanks a lot to Mr Jay Hughes for the tutorial about using indirect addressing... I'm using CJ1M, trying to create some program to save data.... for example saving data from D1100 to D2000. Let say for the first product, using indirect addressing I save the data between D1100 to D1199. When the second product detected, the data will be save between D1200 to D1299, and continue with this pattern until reaching D1900-D1999. My problem is I try to transfer the data backward. Using XFER, for the first product data (D1100-D1199) I want to transfer to D1000-D1099, continuing with the second product data transfering to D1000-D1099 and the first data shifting to D1100-1199, like using WSFT command,so the new coming product data will be save inside D1000-D1099. Also because my data area I want to use until D2000, I want to clear the oldest data (when the 10th product come, the first product data all clear). I'm new to programming plc and still need to get use in using command. Any suggestion is appreciate... thanks again and sorry for my poor english

Thanks For your help Jay... I'll try to figure and make it works....

Hi all , firstly sorry if my english is difficult to understand.... I'm not so good in english writing.... I'm new at PLC and I'm using Omron CJ1M-CPU23.... CX-One programmer.... Actually I try to create a program with plc and touch panel using NS-designer for data logging.... I've create a ladder program using WFST command in memory area from d100 to d199.... so my data (100data) will be save in the selected memory area and everytime new data come will be shift.... but in my touch panel, I just want to show only 4 data from d100 to d103 (latest data). Also I want to create a button that if I push it for example [+1] the panel can show data from d101 to d104, and continue changing everytime I push the button (shifting is the word I guess). And shifting backward again if I push [-1] button (like scrolling button)... I think using XFER,MOV and ADD [+ command in cj1m] I can create it but I still can't (beginner). In my attachment is the touch panel example, [+4] button is for viewing 4 data before.... and so on.... Any suggestion is appreciated.... for beginner like me, this kind of homepage is very useful.... keep on the goodwork everybody...... Thanks again....
