What are you trying to communicate with?
Thank you.The SDO message I am sending is 2 bit bytes Byte 1 is OxO1 and byte 2 is 0x00
This gets the buss started and into the state where it will send and recieve.
The message to set the timer to 0 is an 8 byte messagd in the SDO format. byte1 is 0x00, byte 2 is 0x49, byte 3 is 0x31, and the rest of the bytes are all 0x00. I had 2 curtis devices on my buss so i had to send a message addressed to each one.
The MOSI message is PDO1 and PDO2. Bothe are 8 bytes and all of the bytes are 0x00. Since i did not need to send any data to the curtis they can all be 0. When you send PDO1 the device will respond with SDO1, etc. to send them as ofted as you want to read the default parameter in the curtis mesage.
Hope that helps.
