Hello Ivolvic, You can use the PLC job 51 for changing screensfrom the plc. See B-9 Communication Tweety |

Hello lvolvic; In reply to question number 1): Area pointers are "bit maps" that you create in the PLC; each bit in the area pointer for alarm messages for example is linked to a message defined in the OP 17. This is how the Protool manual (for the OP 17) explains it: HMI ProTool How to configure text-based units 4.7 Available area pointers: ... Alarm messages You can configure an alarm message for each bit in this data area. The bits are assigned to the message numbers in ascending order.As soon as the PLC sets a bit in this data area, the operating unit recognizes that the assigned alarm message has "arrived". Conversely, the operating unit interprets the message as "departed" after the bit is reset on the PLC. If you define the Alarm messagesarea pointer as DB1.DBW0 in your PLC(as in your example) you are reserving 16 messages, each linked to a bit in that word (DB1.DBX0.0 to DB1.DBX1.7). When you set bit DB1.DBX0.0 in your PLC program, alarmmessage number 1 defined in the OP 17 is active; when you reset the same bit the message number 1 is not active. When you set bit DB1.DBX0.1 in your PLC program, alarmmessage number2 defined in the OP 17 is active; when you reset the same bit the message number2 is not active. And so on. Hope this helps, Daniel Chartier |
