Getting "Access denied to system ..." whem I'm using AC800M HI
I get "Access denied to system ..." when I'm using a system with AC800M HI (PM865 + SM811) with SIL1-2 or SIL3 application. I can access to controller only with a complete reset and without using SIL tasks and applications.
Thanks for your help.
I thought this will be helpful for you in dealing with HI controller. Please go through Access Management in the operation user manual.
And the following is the PIN information of SM811:
PIN Designation Description
1 UP Common I/O power
2 I1 Digital input 1 (Reset all forces)
3 I2 Digital input 2 (Access enable)
4 I3 Digital input 3
5 O1 Digital output 1 (Any force active)
6 O2 Digital output 2 (System alarm)
7 ZP Common I/O return
I am doing my First Safety Project.
Its good to have such little Important points for learning .
However we are having a Hardware Enable Key placed in our Safety Panel,which solves the above issue too.
I will like to ask some things:
1) Is it mandatory to have Reauthenticate download as FALSE.
It is showung True in my system. As far as I know, we made it True only when we are working on SoftController.
Should I make it to FALSE
2) I have prepared a simple logic creating a Non-SIL application : A Digital Output Channel IO gets High(true), when it satisfies two or three Required Inputs.
My problem is that even when All necessary inputs are OK, the Output dont gets High.
Rather if i make that DO high, by just using a MOVE block,then it gets High.
3) We have installed a Compact HMI FP4 system on a separate system,and we have made OPC connection OK between these two PC's. But when I tried to operate any Faceplate /Toggle button to Make any IO to True/False, it dont gets operated.
4) I tried proceediing with making connection through another OPC tool, it gets connected to OPC server, but when i attempted to browse in the Variables of program, it shows a Error: "Äccess Enable error".
Kindly support !!
