7.5.3.4. Locking EEProm memory

If an PLC-controll writes or programs parameter, Cams or Delay-Times cyclical (eg. DC300 or CP16)
the unit's EEProm-Memory will be destroyed after a short time. If cyclical programming is, for a certain
reason, necessary, you therefore have to lock the EEProm.

Therefore select

S-EE

in menu

"unit configuration"

and change it by pressing

to

"locked"

. If the

EEProm is locked,

all

data will only be written to RAM and will be deleted if the voltage is switched off.

Attention:

After having finished a complete deleting, this value is set to

"unlocked"

again.
