hi, i am currently trying to adapt an i/o device for a project. the node id is unknown and there is no eds file available. no data is being emitted from the device as a giveaway, the baudrate is known but useless without the node id. is there an sdo request available to determine the id? i cannot get the device to leave pre op status even with a global nmt request. please help. no hair left.
not looking forward to setting up function blocks for this :( oh well we will prevail.
I am also having the same issue. I have read somewhere that can variable lists are not available on 3.5, surely this isn't the case? Hoping for some enlightenment.
hi all, i am trying to create a program using codesys control win as the plc and ifm cr2012 i/o modules as the outside interface. the data is trasmitted via canopen, i am using the provided eds files for the configuration of the i/o modules. i am having no problem receiving binary inputs but dont seem to be receiving any values for the analogue inputs. i can see on my pcan software that the data is being transmitted but it isnt appearing on the mapped variables in the device? any ideas why would...
hi all, i am looking to create a HMI collecting and transmitting data over canopen. the hmi i am using is programmed via codesys 3 while the application for the plc is programmed via codesys 2.3 i am used to codesys 2.3 which provides function blocks for the reception/transmission of the data bytes in arrays which you can use. i cannot seem to find this library on codesys 3.5, is there a seperate library for this available for download or am i missing something. thankyou
hi all after a bit of advice, i am reading byte values which are sent as a word from the transmitting node in a can packet and am unsure how to combine the 2 byte values once they have been received to create a word which can be used as inputs to function blocks. i am sure there is a simple solution but i cant seem to figure it out. thankyou
Thanks for your reply, the preference would be to have the machine ignition supply to somehow boot up the PC so the user would not have to toggle the computer power each time the machine is started/stopped. How is this possible? Thankyou
Hi, I am using codesys HMI to control and display values on a mobile machine, i am planning to use a windows laptop as the machine interface, is it possible to boot the computer directly into the HMI application triggered by the 'ignition on' of the machine and then following that shutting the computer down with ignition off? thanks
