How to judge whether the remote module is connected through the program

Siemens PLC judges by DeviceStates function blocks

mitsubishi L series PLC cc-Link ief basic

SM1704 to judge the network status, each station through the SD1704.0-1704.F, SD1705.0-SD1705.F judgment

EtherCAT bus

beifu PLC has variable judgment: WcState = 0,State = 8 module bus connection


pn protocol siemens PLC STOP mode remote module how to output?

Output disconnected

Communication rate between EX Series modules

6MB/S

What functions the PROFINET module supports

Support RT, MRP


Communication Rate Setting of CC-Link Module and Logical Station Problem of Fixed Station

Fixed logic stations: 4 stations

variable logic station: configurable 1-4 stations

the EX series module is a remote equipment station, and the number of occupied stations can be set to 1-4 stations.

The FS FS1 series is a remote IO station and occupies 1 station. Dial switch 0-4 range setting

fixed logic stations: 4 stations

variable logic station: configurable 1-4 stations

the EX series module is a remote equipment station, and the number of occupied stations can be set (1-4 stations)


EX Series supports analog measuring range

Voltage type: 0-10V, 0-5V;± 10V, ± 5V

current type: 0-20mA, 4-20mA


the above ranges all support 12BIT and 16BIT resolution


Whether the PROFINET and EtherCAT have disconnection output state setting function

The output status of the module after a bus disconnection can be configured:

1. Keep the state before disconnection

2. Output 0

3. Output 1

What protocol needs to be installed with a description file

PROFINET: GSD files to be installed

EtherCAT: XML files need to be installed

CC-Link IE Field Basic: Requires installation of cspp files

DeviceNet: installing EDS files

EtherNet/IP: Install EDS file

CC-Link: No need to install the description file, only need to set the dial switch


EX Series Power Supply Issues

EX adapter power supply is divided:

system power supply: provide system power supply and communication processing for expansion module.

I/O load power supply: Provides power to the sensor solenoid on the expansion module.

If the customer power adapter has sufficient power:

the system power supply provides a maximum of 2A current.

The I/O load power supply provides a maximum of 10A.

For example: customers need to drive 100 solenoid valves, solenoid valve coil current 100ma. At the same time, the output current is 100 * 100ma = 10A. At this time, the power supply module should be added.
