1.9 Addresses word/bit of PL260 for protocol Modbus RTU
The following tables give all data (word and bit) which may be entered via
Modbus protocol. For all data the table gives reading/writing elements and
the value assumed at starting of PL260. According to initialization value at
starting, the following options are given:
1. “ROM” fixed value defined by program.
2. “EEP” value stored on Eeprom for 10years even in absence of power
supply
3. “TAMP” value stored on Ram memory with buffer battery. These data
are stored in absence of power supply for a limited time (approx. 4
months)
4. “?” value of these data is unknown at starting
5. Defined value, The value assumed at starting is the value defined in
the table.
