2 Functions of Devices in DVP-PLC
DVP-PLC Application Manual 2-83
Device Description Latched STOP → RUN RUN → STOP
D1067 Operational error code None Cleared Latched
D1068 STEP value when operational error occurs None Latched Latched
2. Error code explanation:
D1067 error code Cause
H’ 0E18 BCD conversion error
H’ 0E19 Divisor is 0
H’ 0E1A Use of device exceeds the range (including E, F index register modification)
H’ 0E1B Square root value is negative
H’ 0E1C FROM/TO instruction communication error
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/EH/EH2/SV).
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 EH/EH2/SV)
D1102:
Number of data read from file register K0 ~ K1,600 (for SA/SX/SC)
Number of data read from file register K0 ~ K8,000 (for EH/EH2/SV)
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 EH/EH2/SV)
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.
