128 Causes is the maximum supported by the product. You must have a very complicated plant to have more than 128 causes in a single matrix. Hopefully this suitable for your safety design: I suggest you split up your matrix into multiple matrices. You can run multiple safety matrices in one S7-41x controller as long as you have enough execution time in your safety runtime group/OB. If while splitting the matrix you have effects that needs to be touched from both matrices and can't get around it by optimizing the method of splitting up, you can cascade causes to effects from one matrix to the other as causes to pass through. Keep in mind this will change the response time of your safety code and must factor this in when verifying your programming meets the safety requirements of the plant. |
If my post helped you, please rate. Thanks. |

Hello Wahbi, 128 Causes & effects is a System behavior and can't be increased. https://support.industry.siemens.com/cs/de/de/view/109766685 If you need more causes & effects, you can use a multiple matrices structure. This means you connect several matrices together via external connection tags. e.g. Matrix 1: - Cause 1(Matrix 1) /input 1 -> Effect 1(Matrix 1) - Cause 2(Matrix 1) /input 2 -> Effect 1(Matrix 1) - Cause 3(Matrix 1) /input 3 -> Effect 1(Matrix 1) Connection: Effect 1 of Matrix 1 (ext. connection) to Cause 1 of Matrix 2 (ext. connection) Matrix 2: - Cause 1(Matrix 2)/ effect 1(Matrix 1) -> Effect 1(Matrix 2) /output Tag1 - Cause 2(Matrix 2) /input 3 -> Effect 1 (Matrix 2) /output Tag1 - Cause 3(Matrix 2) /input 4 -> Effect 1(Matrix 2) /output Tag1 So you can increase the numbers of possible causes & effects. However, you should note the corresponding voting. Causes and effects should be bundled in a matrix meaningful. Greetings |

Dear Technodrome, How can I do the ext connections wthout input/output tags? |
Best Regards, |

Dear WPLC012, you need one Cause/Effect and write in the Tag field a # before your wanted Safety-matrix output/input Name See attached picture. In Safety Matrix 6.3 is this done automatically, if you choose external connection. There you just have to enter any name.
