Configured, I Used GRT1-ROS2* for slot 3 So what is the Address Assignments? |

Hello MrBooth; I did mention earlier that I am familiar with Profibus connections, not with Omron equipment.There is a point where you, being the one that wants to intorduce Omron equipment ias a Profibus slave, must do due diligence and try to understand how this equipment actualy works. I have done a bit of investigating on the web, which you could have done yourself, to find information on the I/O modules you have selected for your GRT1-PRT slave. The following document provides some answers: https://assets.omron.eu/downloads/datasheet/en/v4/p15e_grt1-_smartslice_remote_i_o_datasheet_en.pdf The screenshot below is extracted from that document. It shows that the GRT1-ROS2 is a 2-point relay output module, so only 2 points are availabe for commands, even though it reserves 2 bytes in the pofibus configuration. For its part, the GRT1-ID4-1 is 4-point PNP input module, even if it reserves 2 bytes in the Profibus configuration. The screenshot also shows the wiring diagrams for these modules. Unless you can access more detailed information on the Profibus connections for each of these modules, I suggest you connect 4 sensors to the -ID4-1 and valdate (with a VAT table, for example), which input addresses actually correspond to each input signal. Then connect two loads to your -ROS2 modules, and test which addresses command the 2 outputs. Hope this helps, Daniel Chartier |

Hi Daniel, "I suggest you connect 4 sensors to the -ID4-1 and valdate (with a VAT table, for example), which input addresses actually correspond to each input signal. Then connect two loads to your -ROS2 modules, and test which addresses command the 2 outputs." Yes that is my next task, I have updated the Matrix as shown in the XLS AttachmentPRT1.xlsx (155 Downloads) |

Hello MrBooth; Follow the suggestions found in these discussions from the forum, you will ses how to find the Cycle/Memory tab in CPU properties, allowing you to select a byte address to act as a clock memory. https://support.industry.siemens.com/tf/ww/en/posts/clock-pulse-in-step-7-s300/128474 If you choose MB20 for example as the clock byte, each bit in this byte, M20.0, M20.1... M20.7 will flash at a different rate. The second link has an entry with a screenshot sowing the fifferent frequecies assigned to each bit in the clock byte, specifically M20.5 will flash at a ratr of 1 Hz. Hope this helps, |
