Maximum Number of Global Objects in Sigma Controllers and Integration Controllers (ICs)

[Product_Support]

Issue

What is the maximum number of global objects that can be received by a Sigma controller or Integration Controller (IC)?

Product Line

Satchwell BAS & Sigma

Environment

• Sigma UNCX96 controllers
• Sigma UNCX32 controllers
• Sigma Integration controllers - All types

Cause

This limitation is due to configuration and engineering constraints within the Sigma system architecture.

Resolution

• Maximum Received Globals:
  Each Sigma controller or IC can receive up to 50 global objects.

• Transmitted Globals:
  There is no fixed limit on the number of global objects a controller or IC can transmit. However, when designing and engineering a Sigma system, it is essential to consider:

  • Controller communication load
  • System performance impact
  • Network traffic and latency

Proper planning and testing are recommended to ensure optimal system performance when transmitting a large number of global objects.

Additional Notes

• This limitation applies only to received global objects.
• Engineering best practices suggest minimizing unnecessary global object usage to reduce controller load and improve system reliability.
