  1. We have a few of machines using an AEM 811 analog input card, which is a intelligent module with its own processing capabilities such as input configuration for each channel as well as scaling and threshold detection. According to the documentation the card should function as follows. After power-up a default configuration is loaded and status bit is set indicating a default configuration is loaded. The program then stops the card, transfers the required configuration via a text-block exchange. If the card receives a valid configuration is sets a status word to 'FE' and clears the default bit and the waiting for configuration bit. It should also set a text-block bit to one indication a successful transfer of the configuration data. The program can then re-start the card and begin using the acquired input data. Everything appears to be working except the text-block bit indicating the receipt of the configuration data. This will not allow the card to start. We have three machines which are identical in this regard and we have two spare cards. The spares will work in the other two machines and their cards work also, but none of the cards will work in the third machine. This card sits in slot zero adjacent to the PLC and we have tried changing the backplane with no joy. This is driving me absolutely bonkers. A can't seem to locate many resources familiar with Telemecanique. Does anyone have any ideas? TIA Chris
  2. Hello all, I'm not really a PLC guy but I am helping to maintain and debug some TSX67's in a production environment. We have a TSX67/20 with an AES811 analog input card hooked-up to some pressure transducers and machine tachs. Looking at the program I'm having trouble understanding a certain line of code. The statement is: IF NOT IW0,2,3 THEN IW0,6->W1043->W15050 ELSE IW0,6->W1080 I'm not getting the IW0,2,3 part. It seems to always be 1 or 0 but is it an AND or an OR ? The second comma is not familar to me. Anyone out there who can explain this notation? TIA, chris
  3. We have some 1980's era Telemechanique XBT VB8 HMIs which are getting a little long in the tooth. I understand I'll probably have to start from scratch with a new HMI but I first need to document the current screens and input parameters. I have the software and files (on a 19 lb laptop) but the software is in French. While I could get through a weekend in Quebec on my high school language studies I really could use a manual for this Xtel? software so a can see which machine words are being displayed and which bits are being set, etc.. Any ideas?
