Omron CS1W-DRM21 Procedure Turn on the Master Enable Switch, Master User Allocations Table

User-set Allocations							Section 4-4
Procedure			Step 1: Turn ON the Master Enable Switch
			Make sure that master communications have disabled by checking to see if
			Master Enable Function Flag (word n+11, bit 03) is OFF and then turn ON the
			Master Enable Switch (word n+14, bit 06) to enable master communications.
			Once master communications have been enabled by turning this switch ON,
			they will remain enabled even if the power is turned OFF and back ON again.
				Note Do not turn ON the Master Enable Switch unless master communi-
				cations are stopped. (If the Master Enable Switch is turned ON when
				master communications are enabled, a Unit error will occur and a C5
				error will be displayed on the 7-segment display on the front panel.)
			Step 2: Setting the Master User Allocations Table
			This table specifies the area and first word for each block and the area and
			first word for the Allocation Size Setup Table.
				• Master User Allocations Table
					First word m = D30,000+(100 x unit no.)
Bit	15			08 07		00
m+1 wd		0	0		OUT block 1 area
m+2 wd		First word of OUT block 1					Can be set anywhere past here.
m+3 wd		0	0		IN block 1 area
m+4 wd		First word of IN block 1
m+5 wd		0	0		Area for Allocation
					Size Setup Table
m+6 wd		First word of Allocation Size Setup Table					Can be set anywhere past here.

•Areas and Word Ranges for OUT Block 1, IN Block 1, and the Alloca- tion Size Setup Table

Code	Name	Word range
00 Hex	---	The block is not used.
01 Hex	CIO Area (CIO)	0000 to 17FF Hex (0 to 6143)
03 Hex	Data Memory (DM)	0000 to 7FFF Hex (0 to 32767)
04 Hex	Work (WR)	0000 to 01FF Hex (0 to 511)
05 Hex	HR (HR)	0000 to 01FF Hex (0 to 511)
08 to 14 Hex	Expansion Data Memory (EM)	0000 to 7FFF Hex (0 to 32767) for all
	Bank 0 to bank C (13 banks)	banks

Step 3: Setting the Allocation Size Setup Table

Specify the area and first word in this table at words m+5 and m+6. IN and OUT sizes for all nodes are set here as shown in the table below. The setting range for each node is 0 to 200 bytes (0 to 100 words), although actual size depends on the allocated slaves. The maximum size per block is 500 words. If the size set here is larger than 1 byte, the start bit for all slaves is bit 00 and size is allocated in ascending node address order starting from the beginning of the OUT 1 and IN 1 areas in word units. If the size is set at 0 bytes for a node address, it is skipped the words are allocated to the next address.
