<div dir="ltr">Hi,<div><br></div><div><br></div><div>I want to use a single, quite large (1,024 byte) PDO.</div><div><br></div><div>Does anyone know how to specify such a large PDO in the XML description file / SII EEPROM content ? It seems that only base types are allowed as DataType in a PDO entry (basically any common data type up to 64 bits). Even if using 64-bit ULINTs, that still means I need 64 PDO entries. That's very unwieldy, especially since the data only make sense as an array. I would also like to use a single pointer in IgH master to access it.</div>
<div><br></div><div>Another issue is that there's a second domain of 20 bytes that's being accessed at 100us intervals. Obviously, the large PDO, already requiring more than 100us on the line for a data exchange, is going to prevent the small one from being delivered timely, although the large one only needs to be exchanged once per second. Is there a common way of solving this (perhaps splitting the domain transfer ?).<br>
<br></div><div>I was thinking of accessing the large PDO directly (outside whatever is defined in the XML, directly to a configured SM) and use a series of FPxx commands to exchange data. Is there a way to do this in IgH master ? <br>
