Omron CS1W-DRM21, CJ1W-DRM21 Using Slave Function, User-set Allocations Using the Configurator

Basic Operating Procedures Section 1-6

3.Check Unit Status 2 (word n+11, bit 03) from a Programming Device con- nected to the CPU Unit to see if the master function is ON (enabled). If it is enabled, skip step 4 below and proceed to step 5.

4.If the master function is OFF (disabled), turn ON the Master Enable Switch (word n, bit 06) from a Programming Device connected to the CPU Unit.

Note Execute this only when master communications are turned OFF. (If the Master Enable Switch is turned ON when master communica- tions are enabled, a Unit error will occur and a C2 error will be dis- played on the 7-segment display on the front panel.)

5.Input data in advance into the Master User Allocation Setup Table (words m+1 to m+6) and the Allocation Size Setup Table (specify the position in words m+5 and m+6)

6.Turn ON the Master User-set Allocation Switch (word n, bit 11). Master re- mote I/O communications will begin with the scan list enabled.

7.Switch the CPU Unit to RUN mode.

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. Turn ON the communications, slave, and PC power supplies.

Note Turn ON the communications power supply before turning ON the slave power supplies or the slaves may not go online.

2.Switch the CPU Unit to PROGRAM mode.

3.Create a network configuration file and device parameters file from the Configurator. (Enable master communications in CS1W-DRM21 proper- ties at this time.)

4.Download the above files to the devices on the network. Remote I/O com- munications will begin with the scan list enabled.

5.Switch the CPU Unit to RUN mode.

Using Slave Function

To use the slave function, the Slave Enable Switch (word n+1, bit 06) must be turned ON from a Programming Device. Enable slave communications through CS1W-DRM21/CJ1W-DRM21 properties if you are using a Configu- rator.

With fixed allocations or allocations set in the allocated DM Area words, slave communications must be disabled prior to area allocation and must be enabled following area allocation. The order of the procedure is thus Slave Stop Switch (if slave communications are enabled), area allocation, and Slave Enable Switch.

Note Slave communications must be disabled prior to area allocation when using fixed allocations or allocations set in the allocated DM Area words, and the settings must be read to the Unit when slave communications are enabled. Allocations will not be valid if slave communications are enabled during area allocation.

Fixed Allocations

Use the following procedure to use fixed allocations. Refer to 5-2 Fixed Alloca- tions for details on fixed allocations.

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