[etherlab-users] Bus scanning on Beckhoff devices

I am using Etherlab 1.5.2 master on a Linux Ubuntu. As devices, I use Beckhoff EK1100, EL2004 and EL1014.
During the bus scanning, for each slave, the master tries to read the register 0x0502 (EEPROM Control Status) but he can't because the "Busy" bit of this register is always active. The master has to wait before being able to read the register. Thus, the bus scanning is quite long (around 700 ms for 9 slaves).
Can anyone explain why the "Busy" bit is always active? Is this behavior normal?
Thanks in advance,
