Hi, one of the inovations of the SP1 for STEP7 V12 (Released for Delivery at http://support.automation.siemens.com/WW/view/de/76276623) is the inclusion of Graph for S7-1500. Here there is a very simple sample project to ilustrate how it works. It is possible to simulate it and command / monitore by the Watch Table. Operation i0.0 -> changes from Step 1 to Step 2 i0.1 -> changes from Step 2 to Step 3 i0.2 -> changes from Step 3 to end i0.6 -> stops Graph i0.7 -> starts Graph (again)

Hi, Here there is complement of the open sample program with interlock function. Interlock (from help): " You use an interlock to program conditions on which the execution of the individual actions depends. Actions of a step that are linked with the interlock are only executed when the interlock condition is satisfied. If the interlock condition is not satisfied, a fault exists. You can specify alarms for this case, which are then displayed. The fault does not affect the advancement to the next step, however. Note also that the interlock is automatically canceled when the step is deactivated. Optionally, you can specify that the operator must acknowledge an interlock alarm in order to close it. You also have the option to not program any conditions in the interlock but to still link the interlock with actions. In this case, the interlock condition is always satisfied. " (for example, an "open inspection door" contact that turn off momentanely a motor while the step is active) In this example the interlock is place at Step2 and is command with i0.3 i0.0 -> changes from Step 1 to Step 2 i0.1 -> changes from Step 2 to Step 3 i0.2 -> changes from Step 3 to end i0.3 -> interlock on Step 2 (additional condition to set Q0.1) i0.6 -> stops Graph i0.7 -> starts Graph (again) Attachmentgraph2.zip (1473 Downloads) |

Hi, Here there is complement of the open sample program with supervision function. supervision (from help): " You use a supervision to program conditions with which you can monitor a whole step. If the condition is satisfied, a fault exists and the step remains active. That is, in this case the sequencer does not advance to the next step but instead remains in the active step until the fault has been eliminated. You can also specify alarms and mandatory acknowledgement for the supervision. " (for example an emergency buttom that shutdown the operation) In this example the supervision is place at Step3 and is command with i0.4 i0.0 -> changes from Step 1 to Step 2 i0.1 -> changes from Step 2 to Step 3 i0.2 -> changes from Step 3 to end i0.3 -> interlock on Step 2 i0.4 -> supervision on Step 3 i0.6 -> stops Graph i0.7 -> starts Graph (again)

Hi, the manual "STEP 7 Professional V12.0 SP1" ( http://support.automation.siemens.com/BR/view/en/77991795), has some general information, but no code specific description. An alternative is the online help of the software. |
