Simulator Control for Modicon M580 Safety CPU
Original instructions
About us
Introduction
The dialog box is shown if the simulator is simulating a Modicon M580 Safety CPU.
Representation of the dialog box:
CPU Front Plate
The virtual CPU front plate shows the current state of the CPU in a multi-line display using combinations of the RUN and ERR LEDs:

SAFE
An unrecoverable detected error has occurred in the project. This means communication is no longer possible. The simulated CPU must be reset using the Reset button.
The BACKUP LED is on if a problem occurs during simulated card access or if the simulated memory card is removed.
The I/O, DL, ETH MS, ETH NS, and FORCED I/O LEDs are not supported by the simulator.
Card Acc
The Card Acc LED is on when the card is accessible.
Memory Card
Simulated features of a memory card for the Modicon M580 CPU:
Reset
With this button, you can reset the simulated CPU. This corresponds to a cold start of the CPU where the connection between Control Expert and the simulator is broken, project variables are reset and the simulator goes in RUN (if auto start is activated) or in STOP (if auto start is deactivated)).
Power Cycle
With this button, you execute a power cycle (power off/ power on) for the simulated CPU. This corresponds to a warm start of the CPU (the connection between Control Expert and the simulator is broken and the current project variables remain).
A power cycle corresponds to a power off and power on of a real power supply.
Simulation
Dialog box fields: Host PC name: DNS name of the host PC for the simulator. If the PC has multiple network cards, only the first is shown. Host IP address: TCP/IP address of the host PC for the simulator. If the PC has multiple network cards, only the first is shown. Project name: Name of the project loaded in the simulator.
Connected Clients
The list shows current clients connected with the PC (PCs which are connected via TCP/IP with the host PC of the simulator). The DNS name and TCP/IP address are shown for each client.
