Details
HS840 Head station for LD 800P
A Linking Device consists of one head station and at least one power link module for establishing the connecton of PROFIBUS PA Segments to PROFIBUS DP.
PROFIBUS is standardized accorting to EN 501702. The head station supports all there defined transfer rates from 45.45 kBits up to 12 MBits.
The head station provides one, two or four channels. PROFIBUS PA masters of each channel work independently of each other. The result of this is that reaction times can be reduced drastically.
Up to 5 power link modules can be connected to each channel. Each power link module creates a new segment.
The communication between the head station and the Power Link Modules is realized via removable terminal blocks.
The communication is transparent. Each PA-subscriber is planned like a PROFIBUS DP subscriber and each PA device is directly addressed like a DP slave device.
The head station and the power link modules don’t need to be planned.
It is allowed to mount the head station, and the power link modules within zone 2.
The head station HS 840 permits the operation with redundant transmission line on PROFIBUS DP side.
The channels are working with 31.25 kBaud (Manchaster coded). This saves from additonal time delay within the Power Link Modules.
