2 Functions of Devices in DVP-PLC
DVP-PLC Application Manual
2-105
b) After enabling MODEM (M1184 = On), PLC has to initialize MODEM first (M1185 = On). If PLC fails to
initialize MODEM, the auto-answering function of the MODEM will not be enabled.
c) After MODEM is initialized, it will enter auto-answering mode automatically.
d) If the remote PC is disconnected, MODEM will enter stand-by mode automatically and if the user turns off
MODEM now, MODEM will have to be initialized again when it is turned on again.
e) The connection speed is set by PLC as 9,600bps fixed and modification on the speed is not allowed.
MODEM has to be able to support the speed of 9,600bps and above.
f) The initialization format from PLC to MODEM are ATZ and ATS0 = 1.
g) If PLC fails to initialize MODEM, use the super terminal in PC to initialize it by the format ATZ and ATS0 = 1.
Function Group
Latched Area
Number
D1200 ~ D1219
Contents:
1. The latched area for EH/EH2/SV/SA/SX/SC is from the start address No. to the end address No.
2. See the tables in Chapter 2.1 for more details.
Function Group
Force On/Off of Input Point X
Number
M1304
Contents:
1. For SA/SX/SC, when M1304 = On, peripheral devices, e.g. WPLSoft or HPP, can force On/Off of X0 ~ X17, but
the hardware LED will not respond to it.
2. For EH/EH2/SV, when M1304 = On, peripheral devices, e.g. WPLSoft or HPP, can force On/Off of input point X,
and the hardware LED will respond to it.
Function Group
