Well there's always something to learn. In 15 years of working with Mitsi plcs I hadnt learnt that. Thanks for helping me out. ian

and it worked for me as well. "A MOV statement cannot be the entire rung, there has to be a contact in front" I'm not sure why a contact is required but it has solved my problem. Does this apply to all outputs in misubishi programming? thanks for your help ian

Hi All thanks for your replies. I am using GX DEV v8. The Program is 2 lines at the moment: M9033...............[MOV H0FFFF D0] NOTM9033.........[MOV k0 D0] END This converts OK. When I Add ...[MOV D0 K4Y0] before the end statement this line will not convert. I have tried all combinations in your posts and made sure the I/O racks pointed to are populated with output cards in the I/O Assignment page. The error message is There is a ladder which cannot be converted. correct the instruction at the cursor position. and the cursor is on the last mov instruction. ian

Hi All I want to turn all outputs of a 16 point ouput card on and off in one instruction. This is to test all the slots in a rack and extension rack. I have started by loading D0 with 65535. But what is the instruction to write this data to the outputs. I tried DMOV D0 K4Y0 and MOV D0 K4Y0 but both of these failed to convert. What is wrong with them? thanks ian

Hi Paul & Nathan Thanks for your replies, sorry for the delay responding to your posts. It would never be my intentention to connect this system to the Internet or company Intranet but who can say what will happen. Interpanel comms would be even further from my mind but I suppose more likely once the network is in place. Any way it seems that although my plan would work it is an overcomplicated solution (which I suppose I already knew). The more acceptable solution of realigning the IP adresses of all the panels has now become "Plan A". The largest of our panels has 7 network nodes in the 192.168.1.x range so I will sit down and workout a plan based its structure to apply to all the plant. I will no doubt be back for more advice on this later. thanks ian

Hi all In our factory we have 10 or more panels running AB PLC's (Mainly SLC & a Few CLX). All the panels use Ethernet for local PLC-HMI comms but none of the panels are networked to each other. They all use different IP address ranges which causes some of our maintenance guys problems when trying to connect into the panels via the installed ethernet switches. I have suggested installing routers in each panel so that either of our two laptops could be plugged into any panel without requiring its TCP/IP properties changing. The routers would also be the first step towards networking all the panels back to a central point for data & alarm logging/SCADA/backups. My reason for suggesting routers was so that we did not have to reprogram the existing comms links within the PLCs/HMIs and to provide a common IP Address for our laptops. Also in the future routers would supply subnet isolation for our new process network. That is about as far as my basic networking knowledge gets me but I have been asked to take this suggestion further by specifying routers for the job. Any answers to the following questions would be helpful. 1. Are routers an appropriate solution for this problem, If not what is?. 2. Does the intended use of PLC Programming, Upload, Download, SCADA limit my choice of router. 3. I had envisaged using fixed IP addressing tables rather than DHCP. Is that a good choice? 4. Recomendation of any particular router(s). Cheers ian

Hi Rodney thanks for the extra info all thats left is for me to make sense of the uncommented program. Thanks to everyone for your help I'm sure I'll be back for more. cheers ian

Hi Rodney Thanks for the info, I only had time for a quick glance before i went to work last night. I am not familiar with some of the abbrieviations you used. 1) TCD (Time? Coded Decimal) or (Timer Counter Data?) 2) YMS 3) DCB (Decimal Coded Binary?) and the last two Functions in the program I cant identify are 1) (F670)K124 2) (F670)K131 Cheers ian

Fortunately for me Ive never had to use the hand held programmer. Ive always had the luxury of medoc although it did mean I occasionally had to load a desktop pc into a wheelbarrow and trundle along to the appropriate switch house. Oh happy days, things really were simpler back then. Any how I have some more functions that I have a good idea about but some details would be helpful 1) (F670)K27 2) (F670)K36 3) (F670)K37 4) (F670)K40 5) (F670)K61 6) (F670)K62 7) (F670)K81 Part of this program drives a Uticor 2 line display and most of these functions shuffle the message numbers and data around. Some will be masked outputs driving outputs as binary data. any details would be great cheers ian

Thanks for your speedy reply FNM, I will post some more functions tommorow, Im off to work now on night shift. cheers ian

Hi All in a previous post I asked for some help on F1 functions that did not appear in the manuals uploaded by Crossbow. A member called Rodney helped me out and I am hoping he, or any one else, can do the same again. This is probably going to be the first of a few threads because I am converting an old Mitsi F1 program to run on an AB 1200 micrologic and the following are just two of the unknown functions in it. 1) (F670)K33 2) (F670)K39 any detailed info would be a great help, thanks Ian

Thanks for the info rodney. Where did you source the info from? is there a refrence I can access? cheers ian

Thanks for your help Rodney. It looks like it is just being used as a totaliser in the program. I actually made a mistake in my original post, funtion 2 should read be: setting coil (F671)K702 followed by execution coil (F670)K61. Do you know this one? is it another inc / dec of D702 cheers ian

Hi Crossbow I have been using the manuals that you posted and found them invaluable for identifying some other functions used in the program. The only mention I can find of function numbers below K100 are in some of the additional texts on pages 88 & 93 of the programming manual. It describes (F670)K33 as a data transfer function but gives no details at all of its use or operation. Are there any additional manuals available at meau? I have not been able to find any F1 info on mitsi's uk site. cheers ian

Hi all I am converting a program from an F1 plc to an allen bradley micrologic 1200. In the mitsi there are two functions I cannot identify and I was hoping someone might recognise them! 1). setting coil is (F671)K700 followed by an execution coil (F670)K62. 2). setting coil is (F671)K702 followed by an execution coil (F670)K62. The execution of function 2 is dependent on the outcome of function 1 since it is controlled by M572. I have checked the manuals and all the functions I can find have execution coils greater than K100. cheers ian
