MC Protocol Commands
5.2.1
Command list
The following commands are executable for MC protocol communication of the CPU module.
: Available,
×: N/A
*1 These commands are for QnA-compatible 3E frames.
*2 Devices, TS, TC, SS, SC, CS, and CC cannot be specified in units of words.
Specifying any of these for monitor registration will cause an error (4032
H
) at the time of monitoring execution.
*3 For monitor registration, monitoring conditions cannot be set.
*4 Do not execute monitor registration from multiple devices. If executed, the last monitor registration takes effect.
*5 Set the number of processed points so that the following condition is satisfied.
(Number of word access points) × 12 + (Number of double-word access points) × 14
≤
1920
For bit devices, one point is regarded as 16 bits in word access and 32 bits in double-word access.
For word devices, one point is regarded as one word in word access, and two words in double-word access.
