Moreover, The Unix time value is a 10 digit value and a 32 Bit register is needed. The convert module's output is linked to a modbus slave module.ģ- There is no particular modbus module that you need to link to but the example above links the Vll time source to the Modbus Volts modules for convenience. The latter will generate a pulse every time the variable VLL avg reaches a new maximum.Ģ- The Output of the store module is linked to a convert module to prevent “n/a” values. The diagram below describes the timestamp inserter mechanism.ġ- The Store Module ( Tstamp VLL max) will store the current value whenever it’s triggered by Vll the maximum module. This example can be replicated for any other Modbus parameters such as peak demand, maximum values etc. The time stamp output will be in a UNIX format (defined as the number of seconds since January 1st, 1970, 0:00:00).
#Powerlogic modbus server how to#
The example below shows how to include a timestamp for recorded the VLL average maximum value (Register 40187). Power Monitoring expert, 3rd party OPC servers or 3 rd party modbus servers will assign a timestamp based on the local system time when modbus communication occurs. The user would like to see timestamps for specific modbus registers directly from the device rather than the server. Timestamps are not included in the Modbus protocol. It can also connect to Modbus devices through a Gateway. METSEPM5111 - power meter PowerLogic PM5111, modbus, up to 15th Harmonic, 1DO 33 alarms, MID. Each read/write with the devices is optimized to maximize throughput. This robust server connects to multiple devices using one or more protocols at the same time.
#Powerlogic modbus server driver#
The Modbus driver can connect directly to devices that support Ethernet communications. The MatrikonOPC Modbus Interface provides connectivity to Modbus compliant devices such as any PLCs, RTUs, DCSs, and other Modbus devices. The following tables indicate which data is available in the EcoStruxure Panel Server according to each type of sensors.
#Powerlogic modbus server install#
In order to link keys in redis with modbus object references (coil, discrete input, input register, and holding register) and addresses, the RedisDatastore object uses a modbus_address_map, a dictionary that follows a special convention.ĭatastore = modbus_server.RedisDatastore(modbus_address_map=, redis_host="localhost", redis_port=6379, redis_db=0) Development:įor testing, install a symlink to the package in the python environment using flit: flit install. Modbus Drivers using Ethernet The generic Modbus driver allows the Ignition OPC-UA server to communicate with any device that supports Modbus TCP protocol. The data transmitted by the PowerTag Energy and PowerLogic Tag sensors and Acti9 Active to the EcoStruxure Panel Server depends on the type of sensors. That way, other processes in the system can change the data in the datastore and the modbus_server always has up to data from e.g. In that case, the data needs to be ingested directly in the program that starts the server as in the minimal example above.ĭatastore = modbus_server.DictDatastore()Īn alternative is using redis to hold the data. The simplest datastore is just a dictionary that is filled from the Server object using the various set_-functions described below. The modbus_server pulls the data it serves from a datastore. Set_holding_registers(start_address, values, encoding) Datastore Object
Set_input_registers(start_address, values, encoding) This function can only process one value. Set the input or holding register at address to value using encoding. Set_holding_register(address, value, encoding) Set_input_register(address, value, encoding) MODBUS power meter data logging (easy method) Print version. Set_discrete_inputs(start_address, values) Set Input and Holding Registers MODBUS power meter data logging (easy method). Set the coil or discrete_input at address to value. The product features direct connection of up to 690V L-L without the need of voltage transformers for installations complaint with CAT III, allowing more free panel space for the user. The thread does not block the main thread, but it prevents the program from exiting until s.stop() is called. Product Description PowerLogic PM5000 is a range of three-phase standard DIN 96 x 96mm panel mount meters. Start and stop the server thread which accepts requests. If the datastore is not explicitly given, an empty DictDatastore is instantiated and used. Panel Server supports custom alarms in custom models created in EPC-Web software.
