Can anyone help with this strange problem? I've just started commissioning a system with an 0BA7 series Logo and a TD HMI I have a number of messages, that are set to display on both the Logo integral LCD and on the TD. On the Logo the messages display perfectly, but on the TD some (but not all) of the text is either missing or corrupted. The only pattern I can see is that the problems are all in bits of text generated dynamically with the "ON/OFF" function of the message configurator. The attached file shows photos of the LOGO and corresponding TD display, at the end is a printout from Logosoft of the coding behind the messages. As can be seen on the photos, messages 1/9 & 2/9 display correctly on both the Logo & TD, but messages 3/9 & 4/9 only show the fixed portion of the text on the TD whilst displaying correctly on the Logo. Comparing the coding it can be seen the method used is identical - all four of the messages reference M flags, yet two of them work and two of them don't. Messages 5/9, 6/9, 7/9 & 8/9 display either some bizarre characters - ÿÿÿÿÿÿÿÿ or nothing at all, but again the coding concept behind all four is identical. Message 9/9 displays more of the bizarrre characters, yet the coding - referencing M flags is the same as used earlier. Have I got a faulty TD, or have I discovered and error in the firmware?

Hello Neil! In the LOGO! 7 the limit of the I/O status is 40. (in the Message text limit is 8) But TD shows correctly only 20 (TD version is 8). (in the Message text TD shows correctly only 4) I got from Siemens the newer TD but is not the TD version of 9 yet. I hope the Siemens will improve this bug for the 9'th version of TD.
