[?]: CP341 and FB7 - problem

Post by maximusalina » Fri May 13, 2011 1:56 pm

Hello dear experts, there is a problem need your help.
Thus, there is a system of 300 platforms, on a rack set CP341 version 2.1.4.
With the help of his liaison with the DEVICE ICP DAS. Use MODBUS RTU. Working satisfactorily. However, when reconnecting the device, the link may not appear, function, and FB7 FB8 return false.
Found in a support simenas following -
"The following corrections have been implemented:
Communication problems would arise during reception with the FB7 (P_RCV_RK), if the RESET input was not statically put to FALSE signal. "
Questions:
1. Has anyone had similar problems, as agreed?
2. whether it makes sense to change the firmware?
3. can anyone help feed the input of R logical unit when an oschibki, and in other cases, zero?
Thank you so much

Итак, есть система на 300 платформе, на стойке установлен CP341 версия 2.1.4.
С помощью него поддерживается связь с устойством ICP DAS. Используем MODBUS RTU.
Работает удовлетворительно. Однако, при переподключении устройства, связь может не появиться, функция FB7 и FB8 возвращают false.
Нашли на саппорте сименас следующее -
"The following corrections have been implemented:
Communication problems would arise during reception with the FB7 (P_RCV_RK), if the RESET input was not statically put to FALSE signal."
Вопросы:
1. имел ли кто похожие проблемы, как решил?
2. есть ли смысл менять прошивку?
3. может ли помочь подача на вход R логической единицы при возникновении ощибки, а в остальных случаях нуля? Огромное спасибо!
