 EC60870-5-101 Implementation Guide 
 Protocol Overview 
 The device implements IEC60870-5-101 protocol with the following key functions: 
 Reading States (Interrogation) 
 
 C_IC_NA_1 (100) 
 Reading all inputs and outputs states
 
 Inputs: 1000-1007 
 Outputs: 2000-2003 
 
 
 
 Controlling Outputs 
 
 Function: C_SC_NA_1 (45) 
 Purpose: Setting individual output states 
 IOA range: 2000-2003 
 Values: ON (1) / OFF (0) 
 
 Command Structure 
 General Interrogation Command 
 Type ID: 100 (C_IC_NA_1)
Qualifier: 20
Cause of Transmission: 6 (Activation)
Common Address: 1 
 Single Command (Output Control) 
 Type ID: 45 (C_SC_NA_1)
Cause of Transmission: 6 (Activation)
Common Address: 1
IOA: 2000-2003
Value: 0/1 
 SCADA system configuration 
 IEC60870-5-101 Protocol Configuration 
 
 Common Address (ASDU): 1 
 Frame format: FT1.2 
 Link Layer Address: according to device configuration 
 
 I/O Points Configuration: 
 For inputs (8 channels): 
 
 Type: Single Point Information (M_SP_NA_1) 
 IOA addresses: 1000-1007 
 Direction: Monitoring (read) 
 
 For outputs (4 channels): 
 
 Type: Single Command (C_SC_NA_1) 
 IOA addresses: 2000-2003 
 Direction: Control (write) 
 
 Verification: 
 
 Check if input states are correctly read (IOA 1000-1007) 
 Confirm control operation for each output (IOA 2000-2003) 
 Verify device responds to General Interrogation
