The variables and their addresses configured on the S7 Endpoint follow a slightly different scheme than used on Step 7 or TIA Portal. If diff is checked, a message is sent if at least one of the variables changes its value. All variables: In this mode, msg.payload contains an object with all configured variables and their values.Care must be taken about the number of messages per second in this mode. If diff is unchecked, one message is sent for every variable, in every cycle. If diff is checked, a message is sent everytime any variable changes. All variables, one per message: Like the Single variable mode, but for all variables configured.msg.payload contains the variable's value and msg.topic has the variable's name. Single variable: A single variable can be selected from the configured variables, and a message is sent every cycle, or only when it changes if diff is checked.The S7 In node makes the variable's values available in a flow in three different modes: You can configure the PLC's Address, the variables available and their addresses, and the cycle time for reading the variables. UsageĮach connection to a PLC is represented by the S7 Endpoint configuration node. NodeJS version 10 or greater and Node-RED version 1.0 or greater is required.
