Check level 0 checks for type A, B, and C errors; check level 1, for type A and B errors; and check level 2, for type A errors only. Peripheral Port The peripheral port must be set to the default communications settings shown Communications below. Functional Ground Terminal Be sure to ground this terminal AC-type PCs only to enhance immunity to noise and reduce the risk of electric shock.

Preparation For Operation The password prevents unauthorized access to the program. Although this is allowed for certain instructions, check instruction requirements to confirm that the program is correct or rewrite the program so that each bit is controlled by only one instruction.

Special instructions instructions, variations 79 instructions, variations LD: Unsigned Decimal Monitor Three-Word Data Modification This operation is used to change the contents of one or more of the 3 con- secutive words displayed in the Three-Word Monitor operation. Page 29 One analog output: The information contained in this section is important for the safe and reliable application of the Programmable Con- troller.

Connect a ring terminal to each terminal screw. In this case, DM was selected. These differences are caused by changing execution conditions. Inputting a New SV This operation can be used to input a new SV xpm2a, as well as to change an Constant SV from a constant to a word address designation and vice versa. Use crimp terminals or solid wires not stranded wire to connect to the PC.

Removing The Terminal Block Wiring and Connections Section Floor Ducts Leave at least vpm2a between the wiring and the top of the duct, as shown in the following diagram.

Programming Example Section Programming Example This section demonstrates all of the steps needed to write a program with the Programming Console. External safety measures must be provided to ensure safety in the system. Specifications subject to change without notice. After completing wiring be sure to remove the label to avoid overheating. The Unit may manal if strands of wire get inside the Unit.

The following diagrams show separate RSC port and Peripheral port configurations, but both ports can be used simultaneously. EC Directives Countermeasure Examples When switching an inductive load, connect a surge protector, diodes, etc. Operating Modes Console will display a message prompting the user manula enter a pass- word. Input the second instruction and operand. Console will display a message prompting the user to enter a pass- word.

Note The standard settings are: Output Indicators The output indicators are lit when the corresponding output terminal is ON. Push the PC forward until the lock snaps into place. The status of the displayed words can be changed at this point. Tighten the terminal screws Operation OK? Refer to Programming Console Operation Errors for details on errors that might occur during Programming Console operations. DIP switch connector output 5. Locking lever 1. Only 10 words, however, can be allocated for input and output respectively.

Page 98 Note a Pins 3 to 6 on SW3 are used to set communications between gen- eral-purpose communications components and the Simple Com- munications Unit. Operation may not be correct if this pin is turned ON.

The maximum current that can be supplied via the CPU Unit power supply connector and the service power supply terminals on the terminal block is mA. If low voltage affects the equip- ment, etc.

Be sure that Overheating there is adequate ventilation for cooling. Push the PC forward until the lock snaps into place. Power cables Floor Ducts Leave at least mm between the wiring and the top of the duct, as shown in the following diagram.

Align the power supply connector with the socket on the bottom of the CPM2C and insert the connector. To remove the power supply connector, grasp the power supply connector not the wires , press on the lock level to release the lock tab on the con- nector, and remove the connector. Note 1. When using other power supplies, be sure to use a DC power supply with sufficient ca- pacity and low ripple. Take external countermeasures to ensure the safety of the system in such an event.

Failure to do so may result in a serious acci- dent. Removing and Wiring a Use the following procedure when wiring a terminal block. Terminal Block 1,2, Loosen the screws at the top and bottom of the terminal block as shown in the following diagram. After wiring the terminal block, insert the block into the Unit and tighten the screws at the top and bottom of the terminal block. Connectors Pressure Connectors 1,2, Align the connector and insert it into the Unit.

Slide heat-shrink tubing over the power supply wires and solder the wires to the appropriate pins on the socket. Heat-shrink tubing Power supply wires Do not allow the common termi- nal current to exceed 1 A. Open the lock levers on both sides of the connector before connecting the cable.

Insert the cable into the connector and press in firmly until the lock levers lock into place. Page Section Wiring and Connections 3. To remove the cable, pull the lock lever out to the sides to release the lock mechanism and pull out the connector. Note Be sure to make connections to terminal blocks and connectors with the cor- rect direction and polarity. Be sure to make connections to terminal blocks and connectors with the correct direction and polarity.

Page Section Wiring and Connections Input Devices The following table shows how to connect various input devices. Special functions for input bits IR through IR are set in Page OFF status for inputs.

The maximum common capac- ity is the same as for other common circuits. Sourcing outputs only Sinking outputs only Power Power supply supply Power Only a MIL connector can be used. The IR area addresses that can be used vary with the Unit used, as shown in the following table. Page The following diagrams show example applications of sink-type transistor out- puts using output bits IR and IR Page Average rectified current must be 1 A.

Inrush Current Considerations When switching a load with a high inrush current in the CPM2C relay output or transistor output model, such as an incandescent lamp, suppress the inrush current as shown below. Tool bus communications are not possible. Connecting Cable The serial devices can be connected to the communications port as a RSC port or peripheral port, as shown in the following diagrams.

The direct connection with a Programmable Terminal is possible by using the communications as a RSC port only not as a peripheral port. Page Section Wiring and Connections Communications Switch Note The setting of SW2 will affect the startup operating mode for all Units with lot numbers of O 31 August or earlier.

Page 2. If the Programming Console is reconnected within 2 seconds of being dis- connected, the previous display will be maintained and the password will not need to be input.

It is also possible to disconnect and reconnect the Programming Console without loosing the current display during long op- erations, such as program checks. At least 80 mm is required. Either connector may be used. About 70 mm is required. Page Section Using a Programming Console Press and hold the Shift Key to input a letter shown in the upper-left corner of the key or the upper function of a key that has two functions. See Buzzer Operation for details. Press CLR to clear the display so that key operations can be performed.

The password prevents unauthorized access to the program. It is assumed here that the causes of any of the errors for which error messages appear have already been taken care of. If the buzzer sounds when an attempt is made to clear an error message, eliminate the cause of the error, and then clear the error message. Page Assigning Expansion Instruction Function Codes An expansion instruction can be assigned to one function code only.

The PC Setup must be set for user-defined expansion instruction assign- ments. Input the second instruction and operand. Press the NOT Key again to change back the instruction back to a non-differentiated instruction.

Page Instruction Search Input the value of the operand from 0 to Then enter the correct input. Restore the hexadecimal display. Press the CLR Key to bring up the initial display.
