Hello everyone, There are some questions I'm running into and I hope I can get some answers, tips and directions. I'm new to Siemens Logo, but I have experience in Fanuc robot programming. A lot in a robot happens with PLC, but that's all based on Fanuc's programming and that is different to LOGO. What I'm trying to create is a user friendly interface to operate a oven. It's a industrial oven and currently we use relays, switches and temperature controls to operate it. All working well, but it's either ON or OFF, I can't set a timer to turn the heater off after 4 hours, read the heater temperature and once dropped below 30ºC the fan can go off. The heater is controlled by a separate micro-computer based Temperature Indicating Controller. This turns the heater off when oven set temperature is reached. When the oven temperature is to low the heater turns on again. To keep things simple now, I want to keep this in place and not use the PLC for this. (I imagie the LOGO could do this as well) What do you guys think of this? Am I doing ok this way? Added the .lsc file as a ZIP Thanks for your input! AttachmentHeater.zip (479 Downloads) |

Here's the suggestion. I only use the F-keys of the TDE, no cursor keys. With F1 (menu up) and F2 (menu down) you scroll to the menu. With F3 you switch the heater on, the time is locked to the selected message text. If the heater is on, you can't restart the time and not change the message text.. With F4 you can break the operation. I hope, this is what you want. AttachmentHeater_V2.zip (536 Downloads) |
