I'm trying to set the catio-a I/O module to talk to a VFD via Modbus but I am at a bit of a loss.
Excerpt from Ethercat sdos
Code:
SDO 0x3000, "Set Modbus reg W"
0x3000:00, r-r-r-, uint8, 8 bit, "SubIndex 000"
0x3000:01, rwrwrw, uint16, 16 bit, "SubIndex 001"
0x3000:02, rwrwrw, uint16, 16 bit, ""
0x3000:03, rwrwrw, uint8, 8 bit, ""
0x3000:04, rwrwrw, uint8, 8 bit, ""
0x3000:05, rwrwrw, uint8, 8 bit, ""
0x3000:06, rwrwrw, uint8, 8 bit, ""
0x3000:07, rwrwrw, uint16, 16 bit, "�"
I got this for the xml file but I get errors reported but eventually axis opens without any syntax issues with
Failed to Execute SDO download size 1, byte0=0 error -5, abort code 06010000
Code:
<sdoConfig idx="3000" subIdx="2"><sdoDataRaw data="00 10"/></sdoConfig> <!-- Address 0x1000 (Swapped) -->
<sdoConfig idx="3000" subIdx="3"><sdoDataRaw data="10"/></sdoConfig> <!-- Length: 16 (Hex 10) -->
<sdoConfig idx="3000" subIdx="4"><sdoDataRaw data="01"/></sdoConfig> <!-- Slave ID: 1 -->
<sdoConfig idx="3000" subIdx="5"><sdoDataRaw data="04"/></sdoConfig> <!-- Type: 4 (Holding Register) -->
<sdoConfig idx="3000" subIdx="6"><sdoDataRaw data="01"/></sdoConfig> <!-- Enable: 1 -->
subIdx 0 = read only
subIdx 1 is a PDO so no need to set in SDOs, PDO definition works
SubIdx 7 is a error count
If you have ideas, please have a go.
Would the VFD need to be connected via rs485? I have not done that yet.
