Hello etherlab-dev I have experienced that the Etherlab EtherCat Master does not release the Slave EEPROM for PDI access like TwinCAT do?
I use Beckhoff ET1100 ASIC's for my slaves. Using the command line tool I can manipulate the Slave register to allow the PDI to read the EEPROM so that my slaves can update the SDO object 0x1018 subindex 4 from EEPROM. >From a ASCII terminal: ~ # ethercat -p2 reg_read 0x500 -t uint16 <-- Read EEPROM config register 0x0000 0 ~ # ethercat -p2 reg_write 0x500 1 -t uint16 <-- Set bit 0 in config register ~ # ethercat -p2 reg_read 0x500 -t uint16 0x0001 1 <-- Now the bit is set, the slave PDI can access the EEPROM My slaves updates the object (0x1018) on a transition from INIT to PREOP ~ # ethercat sl 0 0:0 PREOP + PCM5.1 Power and Control Module 1 0:1 PREOP + PDM5.2 Power and Distributed Communication Module 2 0:2 PREOP + IOM5.1 Input and Output Module ~ # ethercat -p2 st init ~ # ethercat -p2 st preop ~ # ethercat -p2 reg_read 0x500 -t uint16 <-- Bit is not altered by the master 0x0001 1 ~ # ethercat -p2 upload 0x1018 4 -t uint32 <-- Read object 0x1018 subindex 4 - serial number 0x01020304 16909060 <-- My slave serial number I propose that the master by default allows the slaves to read the EEPROM from PDI side by setting this bit (register 0x500.0 = 1) when it is not used by the master.
