2 Functions of Devices in DVP-PLC
DVP-PLC Application Manual
2-104
Contents:
1. SA/SX/SC can use external interruption to store the present value in the middle-high-speed counter into D1180 ~
D1181, D1198 ~ D1199
2. The function:
a) For SA/SX, X0 (pulse input point) has to work with X4 (external interruption point), C235/C251/C253 (high-speed
counter) and I401 (interruption No.). D1180 and D1181 are the registers to store the 32-bit values. X1 (pulse input
point) has to work with X5 (external interruption point), C236 and I501. D1198 and D1199 are the registers to
store the 32-bit values.
b) For SC, X10 (pulse input point) has to work with X4 (external interruption point), C243/C255 (high-speed counter)
and I401 (interruption No.). D1180 and D1181 are the registers to store the 32-bit values. X11 (pulse input point)
has to work with X5 (external interruption point), C245 and I501. D1198 and D1199 are the registers to store the
32-bit values.

DVP-EH/EH2 series MPU
DVP-F232 interface
2. Special M for MODEM connection for EH/EH2:
Device No. Function Note
M1184 Enable MODEM On: The following actions are valid
M1185 Initialize MODEM Off: Initialization is completed
M1186 Fail to initialize MODEM Off: M1185 = On
M1187 MODEM initialization is completed Off: M1185 = On
M1188 Shows if MODEM is connected On: Connecting
Note: The special Ms are both applicable when PLC is in RUN or STOP status.
3. How to conntect (Please follow the steps below):
a) Set “On” M1184 (Enable PLC MODEM connection).
b) Set “On” M1185 (Enable initialization of MODEM from PLC).
c) Check if the initialization of MODEM is successful from M1186, M1187.
d) Wait for the connection.
4. Note:
a) When PLC is to be connected with MODEM, a RS-232 extension card is required. If there is no RS-232
extension card, all special M above will be invalid.
