[@PROTUTO89]

What do you mean Sir ? I did not understand your Question

[@aboodabuibaid3405]

What is 51 for ? I tried everything the same . but i dont what went wrong and it is not working :(

[@adolfoleonhernandezabadia5360]

Excellent OVA. Thank you very much for the support, how can you read the screen number that is active?

[@nareshsekar4807]

Hello sir, if I click connections, it is not showing HMI_Connections_1. If I click add new then its showing only Connections_1. It is not showing any values in the tab of “Station” and “Partner”. If I click “Job mailbox” the access mode changes from “symbolic access” to “absolute access”. And the optional arrow is also not visible to change the mode from “symbolic access” to “absolute access”.

[@elvinchandra8743]

in my case, the access mode automatically become "Absolute Access" instead "Symbolic Access". so i cant do your way like this. i'm using Simatic S7 300 and KTP900 Basic PN. is there any explanation why i cant do this?

[@nareshsekar4807]

i am facing the same issue. have you got it solved now?

[@patrikvogel2415]

I can not figure out why he uses this particular Area pointer. i can also not figure out what the 51 and 0 values mean. Siemens help does not seem to cover HOW to use the area pointers. only that they can be used

[@153amolskumbhar]

Why mailbox used for auto screen navigation, there is separate option for screen number

[@plcprogramhm4632]

can u tell me what other logic we can use this

[@256venki]

What is P TRIG tag?? what is 51 start value ?? Where we need to select screen number in function program? (Ex: if we press Estop Stop (digital bit) then screen should change to alam display screen ) how???

[@PROTUTO89]

P_Trig : means the positive Edge instruction. we use Positive Edge here to ensure that the action will be executed just once , when the ENABLE goes from 0 to 1.And we can change HMI screen through PLC if an alarm appears per example , or in the end of the Automatic cycle , when we want to display report or something like this.
