Frequently Asked Questions (FAQ)

Q1: What types of automation systems is 07KT94 suitable for?
A1: It is suitable for small to medium-sized industrial automation systems, particularly in intelligent decentralized control scenarios such as process automation and factory production control.

Q2: Does it support analog input configuration?
A2: Yes. It supports up to 8 analog input channels, configurable for voltage, current, or Pt100 temperature sensors via KW86 system constants.

Q3: Which communication protocols are supported?
A3: MODBUS RTU is supported through the COM1 and COM2 serial interfaces.

Q4: Is a high-speed counter supported?
A4: Yes. Various counter modes can be set using system constant KW85.02, including up/down counters and encoder inputs.

Q5: Is watchdog monitoring available?
A5: Yes. Task cycle monitoring can be configured using KW80 system constants for overrun protection.

Q6: Will variable data be retained after power loss?
