Hello everyone,
I have been developing a system with S7-1500 cpu. I have gotten through many problems, and yet the 3 big concepts, I couldn`t solve.
MODBUS TCP problem
I wanted to get data from a bender iso685 model product using modbus tcp.
I tried with modbus poll, and I could get data from the device, but not with my plc.
the plc program looks like this:
it gives either status 7004. 7005 or status 8383.
the DB_MODBUSTCP_CONNECT database that I used: (my hardware interface id is 72)
I have also changed the hardware ID accordingly to the bender iso685 in the MB_CLIENT_DB_READ resource database.
I use a Array[1..20] of Word type array for the data to write in. Couldn`t see anything other then 16#0000 on it.
I just want to read the data form the iso685 device. anyone have any advice on this? I would really appriciate it.
rs485 problem:
my blocks for rs485 looks like this:
I am getting status 7001 and errors 8188 8281. Again help would be really appreciated. In tia portal they say it is about the port mostly. but the port I use looks like it functions. Couldnt find out what the problem is with it. I don"t see lights on it but many people said it is normal in TIA.
also here is the modbus rtu settings in bender device:
the last problem: the Profisafe problem
my problem with the Safety programming, is that I am getting errors on my F-IO`s and becouse of this I cannot get the cpu to run.
It might be becouse I havent connected anything to the F-IO`s, but I really don`t know. the TIA forum had many many different answers, and I am trying most of them, some of them are not even doable for me. I have de-activated the F-cpu in the S7 1500, to be able to try out other programs.
when I activate F-capabilities of the cpu; and download the program to it, it doesn`t go in run mode anymore. there are lots of errors that it gives, I am out of pictures to post here, but I will eventually give more data about this issue.
Thank you for being here and reading my post, I would really appreciate any help and will be as fast as I can to reply and try out solutions in order to finish my projects technical initialization part.
