Hi. I have make a program three weeks ago and everything is ok. To day i make some changes and write 2 FC more. Then i download it to the plc and the other FC are doing Wrong Things. TheFC that i have make extra have now error and if i compil the project i have now errors. It is a scaling thathave make. If i download the extra blocks to the cpu, then are some S/R functionsthat not want to work in other FC's And if i delete the extra blocksthat i have make and download the program as it was,then are theS/R functions working again. Is this a bug ? What can i do Reset PLC? Thanks Regards. |

Hi, It's difficult to be precise with this data. However my suggestion: 1- check carefully, if you are misuse temp variables (i.e. it is not permited to read a temp variable BEFORE write it in a FC). 2- check if you don't use timers, counter, etc. with same instance DB. In doubt use alwasy FB, place the variables in STAT range, and use timers counters and other FB calls as multiinstance. To reset the PLC, go on to project tree, online access, network card, update accessible devices, online diagnse, funcitons, reset to factory settings |

Hi, Thanks for the reply. The problem is that i want to load FC 105 Scale from your link on te site to the plc. Example load in OB1 or in a other FC. If i do that then some S/R functions in FC's want work . If i load the program as it was, i have no problems. When i want to do a chance then problems start. I try a reset op the PLC. Regards. |
