How to determine whether the remote module is connected through the program
Siemens PLC through the DeviceStates function block to judge
Mitsubishi L series PLC cc-Link ief basic
SM1704 judges the network status. Each station is judged by SD1704.0-1704.F and SD1705.0-SD1705.F
EtherCAT bus
Beofu PLC variable judgment: WcState=0,State=8 module bus connection
How to output PN Agreement Siemens PLC STOP mode remote module?
Output disconnect
Communication rate between EX series modules
6MB/S
What does the PROFINET module support
RT and MRP are supported
Communication rate setting of CC-Link module and fixed station logic station problem
Fixed logic stations: 4 stations
Variable logic station: 1-4 stations can be configured
EX series module is a remote equipment station, the number of occupying stations can be set 1-4 stations.
FS FS1 series is a remote IO station, occupying 1 station. Dip switch The value ranges from 0 to 4
Communication rate setting of CC-Link module and fixed station logic station problem
Fixed logic stations: 4 stations
Variable logic station: 1-4 stations can be configured
EX series module is a remote equipment station, the number of occupying stations can be set (1-4 stations).
EX series supports analog range
Voltage type: 0-10V, 0-5V; ±10V, ±5V
Current type: 0-20mA, 4-20mA
The above ranges support 12BIT and 16BIT resolutions
Whether PROFINET and EtherCAT have the function to set the output state of broken line
The output state of the module can be configured after the bus is disconnected:
1. Keep the state before disconnection
2. Output 0
3. Output 1
What Agreement requires a description file?
PROFINET: Install the GSD file
EtherCAT: requires an XML file to be installed
CC-Link IE Field Basic: Install the cspp file
DeviceNet: Installs the EDS file
EtherNet/IP: Install the EDS file
CC-Link: Do not need to install the description file and only need to set the DIP switch
EX series power problem
EX adapter power supply is divided into:
System power supply: Provides system power for the expansion module and processes communication.
I/O load power supply: Supplies power to the sensor solenoid valve on the expansion module.
When the power of the customer's power adapter is sufficient:
The system power supply provides a maximum of 2A current.
The I/O load power supply provides a maximum of 10A current.
For example, the customer needs to drive 100 solenoid valves, and the coil current of the solenoid valve is 100 mA. When output is performed simultaneously, the current is 100*100ma=10A. Add a power module.
System and I/O power module: EX-0100
