Cam410 is a small simulator for the conveyor band used in Siemens SITRAIN courses.

Cam410 may be connected to a real Step7 300 or Step7 1500 PLC using a TCP/IP connection. The simulated conveyor is controlled by the outputs of the PLC, the conveyor band may be moved in both directions traversing the parts placed on the band. A click with the mouse on any button of the simulated conveyor sets the corresponding input in the connected PLC.

Help

Press Settings button and select a template for addresses: TIA training template or ST (Step7 Classic) template.

Sett also the addresses for Inputs and Outputs according to the real training stand.

Sett the TCP/IP address of the target PLC and the Rack and Slot position of the CPU: usual values are Rack0 Slot0 for S7-1500 and Rack0 Slot2 for S7-300.

Scene selection: Select a simulation view from a predefined list:

• Scene3: a 3D simulation of the conveyor.
• Scene2: a 2.5D simulation of the conveyor.
• Scene1: a 2D simulation of the conveyor.

Cam410hlp is a small C# application used to control the "Safety Inputs" of a simulated PLC.

Safety inputs are protected in the PLC and their value cannot be written from an external application. PLC simulators such as PLCSIM Advanced maintain also this behavior so that Safety Inputs remain protected. Because of this, even when using S7-PLCSIM or S7-PLCSIM Advanced simulators, Cam410s can read both "standard" and "safety" PLC outputs, can write the "standard" PLC inputs but can not write "safety" PLC inputs values.

Cam410hlp is using PLCSIM Advanced API interface to help Cam410s control "safety" inputs of the simulated PLC.

Help:

The first instance (instance 0) from PLCSim Advanced is automatically connected.

• If PLCSim Advanced is not installed Cam410hlp does not start (or crash on start... don't really know).
• When no instance is active in PLCSim Advanced, Cam410hlp waits for one.
• When more than one instance is active in PLCSim Advanced, first one (instance 0) is connected.
• When instance 0 is closed, Cam410hlp connects automatically to the next available instance (new instance 0) (if one is active).

Pairs of addresses are declared in the settings file cam410hlp.ini:

• I_[n]=
• O_[n]=

Addresses may be absolute (starting with character %) or symbolic "PLC tags" (without % as first char)

For absolute addresses only I, M, Q are allowed and only Bool or Byte.

Example for Bool: %I0.0, %M2.7, %Q12.3

Example for Byte: %MB10, %IB12, %QB20

All addresses of type "PLC Tag" (symbolic addresses) must be already present in a Tag Table in PLC, Cam410hlp check the list when connecting to PLC.

After a successful connection to instance 0 of PLCSim Advanced, values of variables declared on I_[n] are transferred to variables declared on O_[n], if possible.

Values are transferred only between parameters of the same or compatible type:

• I_[n]=%M20.0
• O_[n]=%I4.0

The M20.0 value is automatically transferred to I4.0

Versions:

• v220330 [30.03.2022] Fixed "crash on downloading PLC program".
• v210104 [04.01.2021] First functional version.

Task list:

• Bug?: Values from DB block are not accessible as absolute addresses. Values from DB blocks are accessible only as symbolic addresses.
• Fixed "crash on change a PLC tag (or download new PLC program).
