Is there anything I should take note of when using an optical converter module (Type_ NP1L-OL1/OL2) as a hub on one base board?

The base board that plays the role of a hub of optical converter modules is not represented in the system definitions. When the power supply (PS) of the sam... Show Detail

The SPH300EX (Type_ NP1PS-74D) integrates two CPUs. Do I need to create separate project files for the respective CPUs?

Create one project file. There are separate tasks for the respective CPUs and the assignment of POUs to tasks determines the CPU to which the program is a... Show Detail

With the general-purpose communication module (Type_ NP1L-RS□), in what cases does 'C0_ Hardware error detected during receiving' occur?

It occurs when any of the overrun, parity and framing errors is detected in the serial port of a general-purpose communication module. Show Detail

With D300win, when I paste user FBs together with the POU from another project, a compilation error occurs. Why?

A compilation error occurs if the properties of the POU do not match. Specify the CPU type as 'Common.' Show Detail

I understand that an analog input module (Type_ NP1AXH4-MR, etc.) has a signal line breakage detection function. How does it work?

For an analog input range (1 to 5 V or 4 to 20 mA), a line breakage detection function is provided. An input voltage of 0.92 V or lower for the 1 to 5 V ran... Show Detail

Regarding description in the ST language, is it possible to write an expression such as 'variable name + 1' in the brackets of an array?

A description in the brackets of an array must only include values or variable names. Writing an expression in brackets is not possible. Show Detail

When does the port status_ DSR (data set ready) in a structure variable_ RAS of the non-procedural standard expansion FB for communication remain on?

Selecting the DCE mode for the communication parameter_ DCE designation keeps DSR always on. Show Detail

I use an Ethernet module (Type_ NP1L-ET□) in a redundant system. Is processing such as reopening of the Ethernet required at the time of redundancy...

The SPH system automatically inherits information such as the communication ports and reopening processing is not required. Show Detail

Do you have a connection example for the input variable of the compact positioning FB of the positioning FB package?

You can refer to sample project Mptpf4.zwt stored in the ZIPPED folder in the D300win folder. Show Detail

Is the SX bus cable oil resistant?

The cable is not oil resistant so that you need to protect it by covering it with oil-resistant material. Show Detail
