System Limits; Scope Of Delivery - Siemens SIMATIC EMS400S PSB-S Operating Instructions Manual

Overview

1.2 System limits

1.2 System limits
The following applies to PSB-S and PSB-C modules:
● PSB-S module – PSB-C module communication
The communication between the plant segment controller and carrier controller and thus
between PSB-S and PSB-C module is based on the following parameters.
● Power supply
The value refers to the 48VDC input on the PSB-S module. Observe the specifications in
the section "PSB-S module (Page 56)".
The following condition must be met for the load of each connected LOGO!Power power
supply module to maintain the system limits:
Information can be found in the section "Interfaces of the PSB-S module (Page 62)".
Examples:
– 4 A ≥ 0.22 A × 5 PSB-S modules + 0.013 A × 223 PSB-C modules
– 4 A ≥ 0.22 A × 10 PSB-S modules + 0.013 A × 138 PSB-C modules

Scope of delivery

The scope of delivery includes:
● 1 × PSB-S module, order number 6ES7228-1RC52-0AA0
or
● 1 × PSB-C module, order number 6ES7228-1RC51-0AA0

Parameter Value
PSB-S module Maximum 30 PSB-C modules
per RAIL
4 A ≥ 0.22 A × n + 0.013 A × m
The value 4 A refers to the maximum current-carrying capacity of a LOGO!Power power supply
1
module.
When you use 5 PSB-S modules, up to 223 PSB-C modules and therefore up to 223
EMS carriers can be used.
When you use 10 PSB-S modules, up to 138 PSB-C modules and therefore up to 138
EMS carriers can be used.
Comment
Applies to each connected segment. Up to 3
can be connected.
