Basic Operating Procedures Section 1-6

2.Check Unit Status 2 (word n+11, bit 07) from a Programming Device con- nected to the CPU Unit to see if the slave function is OFF (disabled). If it is disabled, skip step 3 below and proceed to step 4.

3.If slave communications are enabled, turn ON the Slave Stop Switch (word n+1, bit 07).

4.Turn ON the Slave Fixed Allocation Area Settings 1 to 3 Switches (word n+1, bits 8 to 10).

5.Turn ON the Slave Enable Switch (word n+1, bit 06) from a Programming Device connected to the CPU Unit.

Note Execute this only when slave communications are turned OFF. (If the Slave Enable Switch is turned ON when slave communications are enabled, a Unit error will occur and a C2 error will be displayed on the 7-segment display on the front panel.)

6.Switch the CPU Unit to RUN mode. Slave remote I/O communications will begin.

User-set Allocations Using Allocated DM Area Words

Use the following procedure to set allocations using the words allocated to the Unit in the DM Area. Refer to 5-3User-set Allocations for details on user-set allocations.

1,2,3... 1. Switch the CPU UNit to PROGRAM mode.

2.Check Unit Status 2 (word n+11, bit 07) from a Programming Device con- nected to the CPU Unit to see if the slave function is OFF (disabled). If it is disabled, skip step 3 below and proceed to step 4.

3.If Slave is enabled, turn ON the Slave Stop Switch (word n+1, bit 07).

4.Input data in advance into the Slave User Allocation Setup Table (words m+8 to m+13).

5.Turn ON the user Slave User-set Allocation Switch (word n+1, bit 11).

6.Turn ON the Slave Enable Switch (word n+1, bit 06) from a Programming Device connected to the CPU Unit.

Note Execute this only when slave communications are turned OFF. (If the Slave Enable Switch is turned ON when slave communications are enabled, a Unit error will occur and a C2 error will be displayed on the 7-segment display on the front panel.)

7.Switch the CPU Unit to RUN mode. Slave remote I/O communications will begin.

User-set Allocations Using the Configurator

Use the following procedure to set allocations using the Configurator. Refer to DeviceNet Configurator Operation Manual for details on Configurator operat- ing procedures

1,2,3... 1. Switch the CPU Unit to PROGRAM mode.

2.Create a device parameter file from the Configurator. (Enable Slave com- munications in CS1W-DRM21 properties at this time.) Then download the file to the DeviceNet Unit.

3.Turn ON the Slave Enable Switch (word n+1, bit 06) from a Programming Device connected to the CPU Unit.

Note Execute this only when slave communications are turned OFF. (If the Slave Enable Switch is turned ON when slave communications are enabled, a Unit error will occur and a C2 error will be displayed on the 7-segment display on the front panel.)
