SyncroLink
The SyncroLink function enables the synchronization of multiple electronic loads (even across series) using a trigger signal to ensure simultaneous operation of the devices. The deterministic behavior is ideal for applications in which multiple loads must be controlled synchronously, for example in tests with multiple load channels of the PMLA series.
SyncroLink uses the physical RS-232 interface to transmit the synchronization signal. Configuration and, if applicable, control are performed via one of the other data interfaces.
One device acts as the SyncroLink master, which generates the synchronization signal, while the other devices act as SyncroLink slaves and receive the signal. A special SyncroLink cable, which is connected via the RS-232 ports of all devices, determines which device is the SyncroLink master or slave.
Advantages:
- High synchronism: The SyncroLink function offers synchronization with a delay of typically less than 300 µs.
- Deterministic behavior: The load input is executed within a predictable time frame.
- No I/O port required: The RS-232 interface is used as the physical medium; the I/O port is not required.
- Galvanic isolation of the devices
SyncroLink Delay
The PMLA multi-channel load series processes trigger signals differently to other H&H loads, resulting in different runtimes. In mixed systems with PMLA devices, these runtimes must be compensated by programming a specific delay time for the PMLA devices.
