Concrete batching plant automation manages recipe selection, weighing of aggregates, cement, water and additives, dosing, and the mixing sequence together. At Enopan, we develop PLC software, HMI/SCADA screens and electrical control panels to suit the plant equipment. For new installations and existing system retrofits, we design production steps, records and operator screens, and carry out on-site commissioning, training and technical support.
Screen and control panel examples from our work
Production control from recipe selection to mixing and discharge
A recipe is selected for the concrete to be produced; the dosing values for each component are defined in that recipe. The PLC performs material feeding, weighing, mixing and discharge according to the plant operating sequence. The operator follows the production stage on the HMI screen.
Recipe values and the operating relationships between field equipment are considered together. When developing the control software, we establish where each material is fed from, how weighing data is obtained and the conditions for moving between production steps. The software scope is therefore based on the plant's actual equipment list.
- Weighing and dosing control for aggregates, cement, water and additives.
- Recipe-based feeding, mixing and discharge sequence.
- Production status and alarm notifications on the operator screen.
Production records and historical reporting
We record weighing values and production information so that previous production can be reviewed. Operator actions and alarm records are tracked in the system alongside production lists and reports. We define the displayed information and report contents during project design.
Live production monitoring and historical record review are different needs. While the operator monitors the running process on screen, the business can access information about previous production through reports. Sharing examples of the records and reports you need at the outset helps clarify the scope at quotation.
We integrate concrete production record transfers to the customer's ERP or accounting software. The data to be transferred and the connection scope are defined according to the software in use and the business requirements.
Automation retrofits for existing concrete batching plants
Software updates, screen upgrades and panel retrofits are different tasks in an operating plant. We assess the required changes using existing PLC/HMI details, electrical drawings, panel and field connections. We separate software changes from work requiring hardware or wiring.
- Updating PLC software and production sequences.
- Revising HMI/SCADA screens and alarm descriptions.
- Automation panel wiring and testing.
- On-site commissioning and checking production steps.
Monitoring, control and service from a phone or computer
We provide access to plant production status and reports from a phone or computer, along with remote monitoring and plant control. We define accessible screens and control functions in relation to the plant infrastructure and operating needs.
When the customer provides internet access, we establish a remote technical service connection through the customer's computer or a remote access device. This connection can be used to review software, assess parameters and analyse faults. Remote investigation is distinguished from work requiring on-site measurement or intervention during the technical assessment.
Engineering, commissioning and handover
During engineering, we consider the equipment list, production sequence, operator screens and panel requirements together. Commissioning checks include recipe selection, transfer of weighing data to the screen, production steps and alarm notifications.
PLC/HMI program backups, electrical drawings, an operating manual and operator training are included in our standard handover. Operator training covers screen use, production monitoring and reading alarm information.
Frequently asked questions
Can automation be upgraded without replacing the whole plant?
We define the retrofit scope according to the condition of the existing equipment. Software or screen changes alone may be sufficient; some systems may also require changes to the panel, wiring or control hardware.
What should I share for a concrete batching plant automation quotation?
Share the plant location, equipment list and your new installation or retrofit request. For an existing system, PLC/HMI details, drawings and panel photographs, together with required reports and any planned production shutdown, help with the assessment.
Let's define your plant automation scope
Share the equipment in your new plant or the changes you want in your existing system. We can assess recipe management, production control, screens, panels and commissioning together.
