Fixed mode (default mode):
Modular ioAdmin allocates 512 memory address sizes based on each I/O module’s sequence in the I/O system.
Slot 0 will range from 0x0000 to 0x01FF and slot 1 will range from 0x0200 to 0x03FF. For example:
If the M-3402 is in position 5 (the 6th slot), then
Channel-0: (0x0200 * 5 + 0) = 0x0A00 (input register map)
Channel-1: (0x0200 * 5 + 1) = 0x0A01 (input register map)
Channel-2: (0x0200 * 5 + 2) = 0x0A02 (input register map)
Channel-3: (0x0200 * 5 + 3) = 0x0A03 (input register map)
If the M-4202 is in position 0 (the 1st slot), then
Channel-0: (0x0200 * 0 + 0) = 0x0000 (holding register map)
Channel-1: (0x0200 * 0 + 1) = 0x0001 (holding register map)
Dynamic Mode
To improve the fragmented memory size and increase performance efficiency, dynamic mode forces Modular
ioAdmin to arrange the same I/O types together, without memory holes. If you have developed your own
program, you can use it to continually retrieve I/O status. The starting memory address is 0x0000. For
example:
If M-2800 (8 channel DO) is in position 0 (the 1st slot), then
Channel-0: 0x0000 (coil map)
Channel-1: 0x0001 (coil map)
Channel-8: 0x0007 (coil map)
If the 1st M-3402 (a 4 channel AI) is in position 2 (the 3rd slot), then
Channel-0: 0x0000 (input register map)
Channel-1: 0x0001 (input register map)
Channel-2: 0x0002 (input register map)
Channel-3: 0x0003 (input register map)
If the 2nd M-3402 (a 4 channel AI) is in position 4 (the 5th slot), then
Channel-0: 0x0004 (input register map)
Channel-1: 0x0005 (input register map)
Channel-2: 0x0006 (input register map)
Channel-3: 0x0007 (input register map)
If M-2801 (an 8 channel DO) is in position 3 (the 4th slot), then
Channel-0: 0x0008 (coil map)
Channel-1: 0x0009 (coil map)
Channel-2: 0x000A (coil map)
Channel-3: 0x000B (coil map)
Channel-4: 0x000C (coil map)
Channel-5: 0x000D (coil map)
Channel-6: 0x000E (coil map)
Channel-7: 0x000F (coil map)
