30336 0x7680 Memory module is full Keypad display: EPM full
Cause Error type/response Remedy
The memory module contains too many param-
eter sengs.
Warning
•
The parameter sengs were not saved in the
memory module.
Execute "Save user data" 0x2022:003 (P700.03)
device command again. This reinialises the
user memory with the current parameter set-
