Vcom Meteocontrol [VERIFIED – 2025]

| Aspect | Limit / Behavior | |--------|------------------| | Max concurrent VCOM connections | 1 (Modbus TCP can handle up to 5, but VCOM serial emulation is single-client) | | Update rate | 1–2 seconds (limited by logger’s internal scan cycle) | | Supported Modbus functions | 01,02,03,04,05,06,15,16 (no extended addressing beyond 16-bit) | | Data loss risk | High if PC sleeps or network jitter >2s; no buffering in logger for VCOM | | Security | No encryption; use only in trusted LAN / isolated plant network |

Critical: VCOM is not supported for parallel cloud logging? No – logger sends data to meteocontrol cloud independently; VCOM only adds local read access. No conflict.


VCOM (Virtual Communication) is a software-based communication interface used within Meteocontrol’s monitoring systems (e.g., in their VCOM Manager tool).
It acts as a virtual data logger or communication gateway that collects data from inverters, sensors, and meters, then sends it to the Meteocontrol portal (e.g., Meteocontrol 360, VCOM Cloud, or SCADA). vcom meteocontrol

In essence:


VCOM doesn't just flash a red light. It categorizes alarms into: | Aspect | Limit / Behavior | |--------|------------------|

Users can set custom escalation rules: "If site X loses 5% production for 4 hours, SMS the technician; if 8 hours, email the CFO."

With the rise of NERC CIP compliance and general cyber threats, the VCOM architecture offers a distinct advantage: Isolation. ⚠ Critical : VCOM is not supported for

The VCOM OSS acts as a secure gateway. It communicates outward to the Meteocontrol cloud (VCOM Global) via encrypted protocols (VPNs/SSL). This separates the plant control network from the public internet, significantly reducing the attack surface compared to open-architecture, consumer IoT solutions.
