8. DEBUGGING FUNCTION
If "Depend on Simulation Data File" is selected for "Link Memory/Buffer Memory", the
access range for each module can be checked by checking the simulation range settings.
NOTE
1) Simulation can be performed only for STEP-RUN.
2) A memory card is required to carry out link memory/buffer memory simulation
using a simulation data file.
Set the simulation data file to the RAM area of the memory card.
3) It is possible to carry out simulation from another station in the network, or
from a serial communication module. However, simulation cannot be
executed from several sites at the same time. With the QnACPU, sampling
trace can only be executed from one site at a time.
4) Simulation is performed by connecting the QnACPU and the peripheral
devices capable of GPP function.
5) Note the following points when executing simulation:
• If direct inputs (DX) and direct outputs (DY) are used to handle inputs/
outputs directly, the device memory is accessed rather than the actual
inputs/outputs.
• No processing is performed for any special function module instruction.
• When a "SP.UNIT ERROR" occurs, FFFF
H is displayed in the module
number area of the common information.
• If "Ignore" is set for the buffer memory access method, FFFF
H is set for
access by instruction and the monitor results.
