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
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 (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.
system and IO power modules: EX-0100
