2-fold Bypass Module 90 300
with non-interacting LED display
The bypass module indicates a present 1-signal on the signal path of the
module by means of the LED I1 (I2). This signal can be bypassed by a linkage
of the connector pins d2-z8 (d4-d8) and by operation of the switch
S1 (S2) on the front plate of the module. The bypassed state is indicated
by the red LED B1 (B2). A common display of all operated override switches
is possible by connections of all pins z10 and d10 to a busbar.
Each override switch is provided with a floating changeover contact connected
to the pins.
All functions on the module are monitored by a micro-controller.
A malfunction is indicated by ERR, the output d28 is on 1-signal and the
relay contact z26-d26 opens.
The output z28-b28 is provided for the connection to the communication
module, e. g. for data transfer to a process control system.
RDY (Ready) indicates the available power supply voltage (³ 20 V).

Communication via MODBUS
Reading of variables
Type BOOL: Function code 1
Type WORD: Function code 3
Events: Function codes 65, 66, 67
Value: 0 always has the contrary meaning
H: hexadecimal value
absolute address: A = p * 256 + rel. address
absolute event no.: E = (p - 1) * 32 + rel. event no.
p = module location no. in the subrack
Reading of all variables
Function code 3, 84 words
since address 2000 H, 3000 H or 4000 H
For a faultless data transfer all 84 words must be read. With that all the
variables of the modules of one subrack are transferred. For module locations
not in use the values 0 are transferred.
Rel. address Data type Value Meaning Rel. event no.
0 WORD 92 H Module type 90 300
1 BOOL 0 none
2 BOOL 1 Module removed
3 BOOL 1 Communication with module not o.k.
4 BOOL 1 Module in slot, communication o.k.
5 BOOL 1 Operating voltage too low, no RDY
6 BOOL 1 Modu |
