20 / 28 page ![]() IB IL SGI 2/P-PAC 7647_en_04 PHOENIX CONTACT 20 18.2 Input words IN1 and IN2 The measured values, configuration or firmware version are transmitted to the controller board or the PC via process data input words IN1 an IN2 according to the configuration. For control word 3C00 hex, IN1 provides the firmware version and the module ID. The module ID for the terminal is 3 hex. Example: Firmware version 1.23 Measured values The measured values are available in IB IL format. The measured value is represented in bits 14 to 0. An addi- tional bit (bit 15) is available as a sign bit. The IB IL format supports extended diagnostics. Values >8000 hex and <8100hex indicate an error. The following diagnostic codes are possible: An open circuit is detected according to the following table: Typical measured values: To calculate the detuning as a percentage for other measured values, please use the following formula: Detuning = Process data value * 0.004 or Detuning = Process data value/250 Example: Detuning = 10000/250 =40% 40% of 2 mV/V = 0.8 mV/V IN1 Bit 15 14 13 12 11 10 987 6543 21 0 Assign- ment (hex) 12 3 3 Meaning Firmware version 1.23 Mod- ule ID 15 14 13 12 11 10 9 8 76 543 21 0 SB Analog value Bit 15: Most significant bit (MSB) Bit 0: Least significant bit (LSB) SB Sign bit Code (hex) Error 8001 Measuring range exceeded (overrange) 8002 Open circuit 8004 Measured value invalid/no valid measured value available 8020 Faulty supply voltage 8040 Device faulty 8080 Below measuring range (underrange) Faulty sensor cable Open-circuit message in diagnostics +U V No GND Uv Yes +U 0 Yes -U 0 Yes +U d Yes -U d Yes Please observe the notes regarding open cir- cuit message under "Local diagnostic indica- tors" Detuning in % of nominal value [%] Input word [hex] Input word [dec] > 130.048 8001 Overrange +130.048 7F00 32512 +100.000 61A8 25000 +1.000 00FA 250 +0.004 0001 1 0.0 0000 0 -0.004 FFFF -1 -100.000 9E58 -25000 -130.048 8100 -32512 < -130.048 8080 Underrange - 8002 Open circuit Nominal characteristic value ±2 mV/V Process data value 10000 dec |
