Setup Device
Flexible Memory Configuration
l
The DMA-EZCCM-001 can hold up to 2 connected devices
l
It will allow different data size configurations for better PLC memory allocation
l
For multiple readers connected, the size will be equal between the two devices
l
“Data Block Size Enumeration” in “Data Block Size” byte setups the size of the User/Result Data Arrays
l
“Disable Reader 2” in “Data Block Size” Enables/Disable control of the second reader to be used in the logic
l
The starting data byte of the second reader depends on the selected Data Block size and is as follows:
Byte Ch1 Byte Ch2/16 Byte Ch2/32 Byte Ch2/64 Byte Ch2/136 Byte Ch2/232
0 24 40 72 144 240
