Mitsubishi — 2.11 Functions of Special Auxiliary Relays and Special Registers

2 Functions of Devices in DVP-PLC Function Group Low Voltage Number M1087, D1100 Contents: 1. When PLC detects LV (Low Voltage) signal, it will check if M1087 is “On” or not. If M1087 is “On”, the content in D1100 will be stored in Y0 ~ Y17. 2. bit0 (LSB) of D1100 corresponds to Y0, bit1 corresponds to Y1, bit8 corresponds to Y10 and so on. Function Group File Register Number M1101, D1101 ~ D1103 Contents: 1. When the power of PLC turns from “Off” to “On”, PLC determines whether to automatically send the content in the file register to the assigned data register by checking M1101, D1101 ~ D1103 (for SA/SX/SC/ EH2/SV/EH3/SV2). M1101:

Whether to automatically downland data from file register D1101: Start No. of file register K0 ~ K1,599 (for SA/SX/SC) Start No. of file register K0 ~ K9,999 (for EH2/SV/EH3/SV2) D1102: Number of data read from file register K1 ~ K1,600 (for SA/SX/SC) Number of data read from file register K1 ~ K8,000 (for EH2/SV/EH3/SV2) D1103: Location for storing data read from file register Start No. of assigned data register D K2,000 ~ K4,999 (for SA/SX/SC) Start No. of assigned data register D K2,000 ~ K9,999 (for EH2/SV/EH3/SV2) 2. See API 148 MEMR and API 149 MEMW for more details. Function Group DIP Switch Function Card Number M1104 ~ M1111 Contents: 1.

When PLC is in RUN status with digital switch function card inserted, the 8 DIP switches amd their status orrespond respectively to M1104 ~ M1111. 2. See API 109 SWRD for more details. 3. When PLC is in RUN status with 4DI card inserted into the input AX0 (photocoupler isolation), the status of AX0 ~ AX3 correspond respectively to M1104 ~ M1107. Function Group Transistor Output Function Card Number M1112, M1113 Contents: When PLC is in RUN status with 2DO function card inserted, M1112 and M1113 will correspond respectively to 2 transistors output points, AY0 and AY1.
