5/12/2023 0 Comments Use click plc as modbus serverNote that the ID parameters allow you to use Aperiodic Ladder elements to run the operations via your program. Note that you can also select several operands by holding down CTRL while clicking them and the right-clicking them. You can convert Periodic operations to Aperiodic, and vice versa. The next image shows Aperiodic operations. To prevent the operation from running, turn this bit OFF. To do this, assign a bit to the operation's Active parameter. Note that while the Active Periodic setting in Properties determines whether the master will run operations periodically, you can prevent an individual operation from running. The next image shows Periodic operations. UniLogic adds a row to the table.Ĭlick in fields to edit and make selections. Select the tab with the desired operation type, and click Add New Operation. You can create both Period and Aperiodic operations. The MODBUS operations you create are arranged in a table. Use this to set whether the MODBUS operations will run via Ethernet or serial port by clicking on the Communications drop-down arrow.Įnter the ID number of the slave to be accessed If this bit is ON, this slave will be accessed when MODBUS operations are run. This is described in the section below, Dropped Operations.įor each slave, add new operations as described below. The Queue options may be used in certain programs that rely on large quantities of data. The default is 500ms, click the field to edit the value.ĭetermines how long the controller will wait for a response from the remote slave. The range is 1-255.Īssign a name to help you identify the slave Use this to select the port for the MODBUS operations by clicking the drop-down arrow.Įnter the ID number of the slave to be accessed. You can suspend a specific operation from running via the operations' Active parameter. You must link a bit to this parameter failing to do so will result in a compilation error. Turn it OFF to suspend all Periodic operations for this slave. Turn it ON to run the Coil and Register Periodic operations according to the time interval you have set in the individual operation. This bit controls, for this particular slave, whether Periodic Operations run or not. Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.MODBUS Slave Properties Window Parameters Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc. Investment is low for the hardware and the software is free There are several reasons why we are using the Click PLC. The entire Click PLC series can be found at this URL: Stride Field Remote IO Modules Powering and Configuring Stride Field Remote IO Modules Unboxing SIO MB12CDR and SIO MB04ADS PID Instruction and Autotuning using Factory IO Modbus RTU Click PLC Master to BRX PLC Slave Communicationįrequency Measurement and High-Speed Count Mode This includes all of the links mentioned in this video.Ĭlick PLC Numbering System and Addressing More information can be obtained on our website. Our Click PLC program will also take into consideration watchdog (communication time out) and power-up events for the Stride remote input and output units. We will look at the Frequency, Count, and Status of this input. ![]() ![]() The output will be on the other remote IO unit and will trigger the input to signal. We will then set an output to pulse on and off at a time range indicated by this analog signal. We will be reading an analog voltage into the Click PLC from the remote IO unit. STRIDE analog input module, 4-channel, current/voltage, 16-bit, isolated, input current signal range(s) of +/- 20 mA, input voltage signal range(s) of +/- 10 VDC, (1) Ethernet (RJ45) port(s), Modbus TCP server. STRIDE discrete combo module, Input: 8-point, 12-24 VDC, sinking, Output: 4-point, relay, (4) Form C (SPDT) relays, 2A/point, (1) Ethernet (RJ45) port(s), Modbus TCP server. Modbus TCP will be the protocol over Ethernet to communicate to the SIO-MB12CDR and SIO-MB04ADS units. We will be connecting two Stride remote inputs and outputs to the Click PLC. Unboxing SIO MB12CDR and SIO MB04ADS Video Stride Field Remote IO Modules Modbus TCP Ethernet Previously we looked at the Stride Field Remote IO Modules Modbus TCP Ethernet wiring and configuration. ![]() Every module operates as a standalone Modbus TCP server and can be configured via a built-in web server. They provide an economical means to connect inputs and outputs to an Ethernet Modbus TCP communication network. The Stride Field I/O Modules are simple and compact. The Click PLC can use remote inputs and outputs from Stride.
