Chapter 1: Outline
The ZM-42/43/52/72/82 series LCD control terminal can display a ladder circuit for a PC (programmable con-
troller) used for facility maintenance.
The LCD control terminal does not contain the entire ladder program in itself, just like the ladder software (JW-
50SP and others). It searches for the ladder program on a network that has the specified coil number, and
displays the reconstructed ladder chart.
The LCD control terminal only monitors the circuit and it cannot write or modify (edit or delete) the circuit. The
LCD control terminal only can be used with a SHARP PC (JW50H/70H/100H, JW30H, and JW20H series). This
function is enabled when the terminal is connected to a PG port on a control module or a PG port on a JW-
20CM/JW-20RS/JW-20MN/JW-22CM/JW-21MN. The link system supports PG port communication protocols.
Features
(1) The LCD control terminal searches for a coil with the same lamp memory address as the switch that is
displayed on the screen. It displays the ladder chart for the network that has this coil.
(2) Specify any coil number by using the numeric keys on the screen. The LCD control terminal will display
the ladder chart for a single network that has this coil on an overlapping screen.
(3) By touching a contact point on the displayed ladder chart, the cursor will move there and display a
symbol comment on the lower line of the ladder chart, if one was registered.
After the cursor moves to the contact point you touched, touching the contact point again will cause the
LCD control terminal to search for a coil for this contact point. When found, it will display the ladder chart
for the network with that coil.
(4) By touching a contact point, the screen will return to the most recent ladder screen prior to the current
ladder screen. (You can review up to previous 8 screens)
(5) The LCD control terminal can display the previous and next circuits for the ladder chart being displayed.
(One network each)
(6) The LCD control terminal can search for the previous and next contact points.
(7) A large circuit that cannot be displayed on a single screen can be scrolled.
(In particular, the ZM-42/43 series LCD control terminals have a smaller display area (320 x 240 pixels).
The range that can be displayed at one time is limited.
(8) Since simple operation procedures are used to display a ladder circuit on a running PC, it is easy to
determine a facility's condition and to find out why a facility stopped.
