Area data (response)
The area data is configured as follows:
CPU Bus Unit configuration (response)
Each CPU Bus Unit has a code assigned to it consisting of two ASCII charac-
ters (two bytes). These codes are given in the numerical order according to
the unit number of the CPU Bus Units (unit 0 to 15).
ID Format
Remote I/O data (response)
The number of SYSMAC BUS Master Units mounted in remote I/O systems is
returned in a single byte (00 to 02 hex) as follows:
Program
area size
IOM size
No. of DM words
EM size Memory card type
Memory card
size
Timer/counter
size
12th byte1st byte
Not used.
Item Meaning Unit
Program area size Maximum size of usable program area K words (1K words = 1,024 words)
IOM size The size of the area (CIO, WR, HR, AR, timer/
counter completion flags, TN) in which bit commands
can be used (always 23).
K bytes (1K bytes = 1,024 bytes)
Number of DM words Total words in the DM area (always 32,768) Words
Timer/counter size Maximum number of timers/counters available
(always 8)
x 1,024
EM non-file memory size Among the banks in the EM area, the number of
banks (0 to D) without file memory.
Banks (1 bank = 32,768 words)
Memory card type 00: No memory card
04: Flash memory

Memory card size Size of the memory card (0000 if there is no memory
card)
K byte (1 word = 2 bytes)
ID for No. 1 Reserved for system (32 bytes).ID for No. 0 ID for No. 15
64th byte1st byte 32nd byte
Bits 00 to 14: Model ID
Bit 15: Unit presence (1: Present, 0: Not present)
No. of SYSMAC BUS Masters mounted (second byte)
Always 00 Hex (first byte)
