• Register 0050: Information on device configuration (read only)
• Register 0051: Information on inputs/outputs, for example number of binary inputs/outputs (read only)
• Register 0065 to 0068: Date and time (reading and writing)
• Register 0071 to 0089: Version information, for example boot firmware (read only)
• Register 0101: Indications regarding device status, for example battery fault (read only)
• Register 0131: Indications regarding status of relay outputs (read only)
• Register 0131: Indications regarding status of relay outputs (read only)
• Register 0141: Controllable messages Indication from Remote (read and write)
