malc cope

Hi Just wondered if anyone has come across this problem before? I have a TP1200 comfort HMI which for some reason refuses to change to Profibus connection, I can select Profibus and any node address but it always stays firmly as MPI, another identical unit I have is fine, the only real difference is that my application was originally downloaded into the unit I am having issues with using MPI

Hi All Currently I have a application where we are using a Pro-Face GP3400 HMI/PLC which has been installed now for a couple of years and all is fine, the unit is currently has a printer connected to its USB port, the client now wishes to save the printed data as a file rather than print it, does anyone if it is possible and how to save this data on a USB memory stick?

Hi From the info thats given I would assume that #SW or Stat_word is declared as the first word in the TEMP area of the interface (LW0), the value of PIW256 is transferred to this word, A L1.2 accesses bit 2 of the second byte of this word and then copies the value of that bit to #running, similarly AN l1.3 copies the NOT value of bit 3 of the seconf byte to #common_alarm, and A L0.1 copies the value of bit 1 of the first byte to #drive_in_remote

Hi I am lookinmg for the most cost effective and simplest way of achieving remote access i.e diagnostics & downloads to0 a number of systems that will eventually be worldwide, the systems are currently configured as a S7-315 DP, TP900 comfort, micromaster drives & Wago Programmable I/O all connected via Profibus. The plan is to connect via a internet connection, the minimum I need to be able do is monitor & download code to the PLC & download to the HMI, would I be correct in thinking that the best way would be to add a IE/PB gateway & Scalance S to the system and connect using VPN?

Hi I need to measure distance travelled on a conveyor, I am thinking of using a incremental encoder connected to a 750-637 module and use the Cam o/ps on the module to trigger when a particular point is reached. The Cam Low and high points will be set in the controller program (750-833) , these will be calculated by using the 750-637 count value at a particular point in the program + (counts = to distance to be travelled) +/- (counts = cam angle). Initially I see no real problem with this other than approaching maximum count value where the Cam low value could be calculated to be higher than the high value, my question is does anyone know what the action of the cam o/p's are under these circumstances?

Without seeing the rest of the FC I would say that the problem is the BEC instruction towards the end of the previous network, if the "End Cycle" bit is not set then the block will be left at this point, as said without seeing the rest of the Function block it is quite reasonable to say there maybe similar statements within the code of the function block, in which case the new network will not be processed, below is pasted from the STL Help text. BEC Description If RLO = 1, then BEC (block end conditional) interrupts the program scan in the current block and causes a jump to the block that called the current block. The program scan resumes with the first instruction that follows the block call. The current local data area is released and the previous local data area becomes the current local data area. The data blocks that were current data blocks when the block was called are re-opened. The MCR dependency of the calling block is restored. The RLO (= 1) is carried over from the terminated block to the block that called. If RLO = 0, then BEC is not executed. The RLO is set to 1 and the program scan continues with the instruction following BEC.

Apologies , should have been a bit clearer 24v is to L+ 0v to M, i.e. 24V between L+ & M

Hi Guys After many years away from S5, I am trying to make use of an old S5-95U I have knocking about, the only issue I have is that I can not get any o/p's to come on. I/P are fine, monitoring the program it shows the outputs on but physically they are not, I have 24V connected to L+ ( terms a1, a11 & b1) & M (a10, a20 & b20), is there something I am missing, or is the unit now only usefule as a rather large paperweight.

Hi Yes it can be done see attached page431.pdf

Hi All I know its very likely this is not the right place but here goes anyway, I was just wondering if anyone has any experience of connecting to sensors & solenoids etc on a rotating machine using ASi via a slip ring, and if so what issues caused problems and recomendations on manufacture of slip ring/rotary joint assembly Thanks in anticipation

Try Wago http://www.wago.us/products/27712.htm

Is it a case of the ethernet module not keeping on transmitting but wherever the data is being recieved it is just not recieving any new data?, I have come acrzoss similar scenarios in the past, regardless of communication method used, where a PLC has failed and the last data recieved is what is seen, Idealy some kind of active watchdog handshaking would be used to monitor the link, so that failures would be noticed earlier

Hi, Hope this helps logo.bmp

Hi All Looking for advice and pointers in the right direction. I have 2 sites , essentially identical, each site has a SLC5/05 connected to a PC running RSView, the PC and the PLC are connected via a bridge to broadband modem. Currently if I need to access the site remotely I use a VNC connection from my laptop and either accedss the RSview or if I need to access the PLC I use Logix on the remote machine. What I need to be able to do is 1. access the PLC with Logix and RSView on my laptop and not have to access the remote machine (i.e in case of failed remote PC) , 2 each site RSView to be able to access the PLC on the other site (i.e same reason as before). Thanks in anticipation for any comments & help

Hi Thanks for reply. Bridge was probably wrong term it, the PC & PLC are connected to a Belkin 5 port 10/100 network switch, model #F5D5131-5, which in nturn is connected to a ZOOM ADSL X6 Router series 1058

Hi All I have 2 identical sites, both controlled by SLC500 connected to RSView 32, I use the messenger part of RSView to send text messages when certain alarms are present, both sites are configured the same, i.e, both send text message to the same number, however only text messages from one site appear to get through, we did have an earlier problem where no messages got through but that was due to the phone number we were using. Now as I said one site is fine, the other not. The site which is not working correctly does attempt to dial out, this is confirmed by the the fact dial outs are appearing on the phone bill. My question is this, could it be a possibility that the modem could be the issue? Other than they are about 5 miles apart, this if anything is the only difference between the 2 sites.

Hi Thanks for your reply & Happy New Year, both sites both have direct lines, no prefixes are used

Not Sure if you are still after help with this, Kempston Controls Tel: 01933 411411 maybe able to help

BAsically a IM flag would appear to be provided for use as a dummy flag, that can be used more than once, i.e if you have a rung that is excessive you can split it by putting the IM flag at the end of the first half of the code then use it as the first contact in the rest of the code

Hi Not sure if this will be what you require, but I have had a very similar application recently, basically I wanted to show various objects (buttons data entry etc) ,depending on the security level, to achieve this I used a macro which would be called on log in to give a tag a value depending on the login level, this tag value was then used in the animation to make the object either visible or invisible. there was also a logout macro to reset the security to its low level. screenshot.zip

Hi Yes we are using a modem and landline, I also tried the first number with the same results, thanks for the number you have supplied, I will give it a try

Hi All Just wondered if anyone can point me in the right direction, basically I have a site which up until recently used to recieve text messages if there were alarms on the system (SLC500 & RSview) , now for reasons unknown we no longer recieve messages, at first I thought it maybe due to Cellnet now replaced by O2 I have changed the dial up number to 07802000332, it would appear the modem etc is working correctly as the 'the phone number is not recognised' can be heard, also this has affected 2 different sites with similat setups, Any Idead?
