Hi, Im new to IFM but have used CoDeSys before. Im trying to get an IFM CR0505 controller and a CR2031 to talk on CAN. In CoDeSys i have set up the CANOpen master and appended a CR2031 into it, which gives me a set of I/O numbers. Using these I/O numbers (%QX33.0) in the programme i try and set the output true but nothing happens, CoDeSys says the output is on. Im leaving the CR2031 in its default stage for binary outputs. I can get the controller onboard I/O to work fine but im having trouble with the CANOpen side of things. I'm hoping someone can point me in the right direction!! Thanks

The way i understand the GSD file is that module 2 is for the control/status and reference/feedback and module 4 is for datalink A. The 700s drive uses 32bit reference/feedback and datalinks which is why i chose module 2 and 4. Module 2 is (2 + 4 bytes) which is why i used 6 bytes in total. The first 2 bytes are for the drive control/status and the other 4 bytes are for the reference/feedback. Module 4 is for datalink A which is (2*4 bytes) so i used 8 bytes in total. I did select the Consistency to be "Entire Length" but i had the same result. Each of the modules is type Input/output. Am i looking at this correctly? Thanks

Profibus_Test.zipAttached is the GSD File and a copy of the project. Thanks GSD file is here (Had to change extension) Copy_of_A_B_0572.gsd.doc

Ive conected the drive to the PLC all the lights are green which indicated that its communicating on the network, however when i look in the input/output areas which the drive is mapped to i dont see anything. Ive used Siemens before where you use function blocks to read and write data to/from the slave, is there anything like this for fanuc? Does anyone have any other ideas what im doing wrong!?

Thanks Russ, How do i specify the length, ive not done much GE stuff befor!!!

I've not really used Fanuc PLC's befor but i have a problem which im trying to solve. Im using a 90-30 plc with a HE693PBM101 profibus master card. Attached to the profibus card is a Allen Bradley Powerflex 700s Drive. Im using proficy ME software. The problem i have is that the feedback from the drive (Motor Speed) is a 32bit real value. The starting point for this address is %I793. If i try to use this as a input into any instruction (Move_Real, Mul_Real, ETC) i get an error because these intructions dont alow %Ixxx as a input. Even the conversion instructions dont allow it. How am i supposed to get the value into a register in the PLC. I may just be really stupid but any help is greatly appriciated!

When you look into the hardware configuration of the profibus node you have set up on the network, you will see the input and output addresses that the configurator will have set up for you. The input address is where the data needs to be sent to. I have nener used the AD drive but if you look in the manual for the drive it will tell you which part of the address is the control word and which part you will send a speed/torque reference to. The output addess in the hardware configurator is where the drive writes data back to, such as the drive status. You can use the move instruction to write the data to the drive e.g mov DB2.DBWX to PQWX

Thanks JesperMP

Hi, Im using winCC flexible - i would like to display diagnostic messages from the PLC. Thanks

Hi, I have a CPU 318 which i have connected to a MP370. How i view the PLC alarms/errors on the HMI? Could someone point me in the right direction please?

Yes you are correct fredrix, my appologies, i forgot all about the rotary switches. You will not be able to change the ip address at all via the software without changing the rotary switches because they have to equal the last byte of the address.

Hi harthenry, Normally the etn21 is programmed through CX programmer. However im pretty sure that you can programme it via the data area of the plc. You could set up fields in the ns which write the data to the data fields. Each time the card is changed however it will need to be restarted. Sorry i carnt be more help but im not near the manual's at the moment, maybe someone else could be a bit clearer.

I tried this aswell but still the same problems

Hi all. I was hoping someone may be able to help with a problem i experienced this morning. I wanted to add a node to a existing profibus DP network. I opened the project via simatic manager went into the hardware config and added a new module. I then downloaded to the plc, which was stopped then restarted after download. Once the restart had finished non of the node's on the profibus network could be seen. So i reverted to the original hardware configaration and downloaded that, still the same thing no node's present. The only way that i could get the node's to be seen was to exit the hardware config and download the entire station. The PLC is a S7 318-2 Any help greatly apriciated. Many thanks

In CX designer i have created a Alarm history table which displays all alarms and works fine. I have read somwhere that it is possible to press the screen over an alarm and jump to another screen. Has anyone else done this? If so could you point me in the right direction please. Cheers
