Installation and Setting Section 10-3

10-3 Installation and Setting

10-3-1 Installation

The following processing explains how to install and remove an Analog OptionBoard.

!Caution Always turn OFF the power supply to the CPU unit and wait until all the oper-ation indicators go out before installing or removing the analog option board.Not doing so may result in an unexpected operation.

1,2,3... 1. Press the up/down lock-levers on both sides of the Option Board slot cover

at the same time to unlock the cover, and then pull the cover out.

2. Check the alignment to make the corner cut of the Analog Option Board fitin the Option Board slot, and firmly press the Analog Option Board in until

it snaps into place.

10-3-2 Setting

To use the analog option board on CP1L-EL/EM series PLC, firstly, it is neces-sary to set the serial communication settings of the CPU Unit in one of the fol-lowing two ways.

Method1: Set by Dipswitch on PLC unit.

For CPU Units with 30 and 40 points, switch DipSW4 of the CPU unit to ON, ifthe Analog Option Board is mounted on the Option Board slot 1 (left side).Switch DipSW5 of the CPU unit to ON, if the Analog Option Board is mountedon the Option Board slot 2 (right side).

For CPU Units with 20 I/O points, switch DipSW4 of the CPU unit to ON.

Note DipSW4 and DipSW5 are OFF at shipment.

Method2: Set the option port communication parameters by PLC settings.

If DipSW4 or DipSW5 is OFF, the relative option port's communication param-eters can also be set by PLC settings in CX-Programmer.

Please set the baud rate of the relative option port at 115200bps in Toolbusmode.

10-3-3 Removing

Always turn OFF the power supply to the CPU unit and wait until all the oper-ation indicators go out.

Press the up/down lock-levers on both sides of the Analog Option Board atthe same time to unlock the Option Board, and then pull it out.

• Recommended ferrules

Note Do not connect bare stranded wires directly to terminals.

■ Terminal Wiring

When wiring the analog I/O terminal block, treat either solid or stranded wiresdirectly.

• To make the connection, press the release button in with a small flat blade

screwdriver and push the line in while the lock is released. Remove thescrewdriver and lock it inside.

• To disconnect the wiring, press the release button in with a small flat

blade screwdriver and pull the line out while the lock is released.

Note (1) Ferrules with/without plastic sleeve cannot be used.

(2) When using stranded wire, twist the core so that the barbed wires cannot

protrude.

(3) Do not solder-plate the end of cable.

The screwdriver shown below is recommended for wiring.

Analog Output Option Board Section 10-6

Wiring for Analog Inputs To prevent noise, 2-core shielded twisted-pair cable should be used. And theshield can be connected to the FG terminal if necessary.

Note (1) If necessary, connect the shield to the FG terminal to prevent noise.

(2) When an input is not being used, short the + and – terminals.

(3) Separate wiring from power lines (AC power supply lines, high-voltagelines, etc.)

(4) When there is noise in the power supply line, install a noise filter on the

input section and the power supply.

!Caution When connecting the analog option board to an outside analog device, either

ground the 0 V side of the PLC’s external power supply or do not ground thePLC’s external power supply at all. Otherwise the PLC’s external power sup-ply may be shorted depending on the connection methods of the outside ana-log device. DO NOT ground the 24 V side of the PLC's external power supply,as shown in the following diagram.

10-8 Startup OperationAfter the power is turned ON, analog option board starts the initialization pro-cess. If the initialization finishes normally, the initialization completed flag inrelated status area (Refer to 10-4-2 Auxiliary Area Allocation: A435 ) will be

set. Therefore, status monitor content must be added in ladder. Only when theinitialization process has finished, user can use the A/D conversion data orwrite the output data.

10-10-1 Procedure

Mount the analog option board into the option port.

Connect to the analog input/output device.

Two methods:

1. DipSW4/DipSW5 set ON: TOOLBUS auto-detect

2. DipSW4/DipSW5 set OFF: Set communication protocol in PLC settings toTOOLBUS, 115200bps

Wait until the analog option board finishes initialization and works normally.

Read the analog input data/write the analog output data.

Note (1) If PLC communication protocol setting is error, the option board will al-ways try to link the PLC, and the error LED will flash.

(2) Only when the initialization process has finished (AR435.14/15 sets on),

user can use the A/D conversion data or write the D/A output data.
