Time Synchronization (CIP Sync/ Motion)

What?

– Gives us System-wide synchronization for CIP-based Networks Time
• CIP Sync™ = CIP Network + IEEE-1588 Sync
• Implementation of IEEE-1588 on EtherNet/IP Networks Object

– IEEE- 1588PTP (Precision Time Protocol) PTP
• “Standard for a Precision Clock Synchronization Clock
Protocol for Networked Measurement and Control Systems”
• “Precision Time Protocol” (PTP) defined by standard.
• Nanosecond resolution
• +/- 100 nanosecond synchronization (Hardware
assist clock)

― Advantages:
• Minimal installation and administration
• Wide spectrum of clock accuracy
• Low cost, high precision

Sequence of Events Module

1756-IH16ISOE /-IB16ISOE (v2.7 or higher)

 Integrated support for CIP Sync

 Allows high precision timestamping with “Real Time” values that originate
from time source on Standard Ethernet

 SOE architectures are simplified with the elimination of SyncLink and GPS
modules which are no longer required in multi-chassis systems

 “x10 FIFO Mode”

 Allows the retrieval of 10 Event Timestamps per RPI (versus 1 today) to
accommodate high speed applications

 Response time improved 10 fold for high speed applications

Provides best of breed technology and cost effectiveness for SOE/first fault
detection systems

What is Peer-to-Peer I/O Control?

Peer-to-Peer I/O Control is output actuation based on input data,
independent of the programmable automation controller (PAC).

Throughput speeds are drastically reduced as outputs are turned on and off without
intervention from the PAC.

Here’s how it works:
1. the input module is configured to “produce” data
2. the output module establishes a connection to the input module
3. the output module “listens” for the data the input module is producing
4. the output module energizes outputs when it “hears” the required parameters

Example Use Cases

Peer-to-Peer I/O Control

Peer control allows outputs on the 1756-OB16IEF module to energize within
50µS of input peer pre-conditions being met.
