Rules Governing the Use of the S5-115F
S5-115F Manual
Variable Addressing
The S5-115F allows you to assign an address to every slot. This is possible if an IM 306 interface
module is plugged into the central controller and each expansion unit. Whether the module is
plugged into the CC or an EU is irrelevant as far as addressing is concerned. There is a flap covering
the address field on the right-hand side of the interface module. On the address field, there is a
DIP switch for each slot for setting the lowest byte number of a given slot.
Note
Input modules and output modules can be assigned the same address.
Address setting on the IM 306
Use switch ( Figure 10-38) to set the number of inputs and outputs of the module plugged
into this slot.
1
Switch in OFF position: 32-bit digital or 16-channel analog module.
Switch in ON position:
16-bit digital or 8-channel analog module.
Use the seven address switches to set the lowest address (the address for channel ”0”) on a
particular module. This sets the addresses of the other channels of this module in ascending order.
Please note the following when setting the initial addresses:
•
32-bit digital modules can only be assigned initial addresses whose byte number can be di-
vided by 4 (e.g. 0, 4, 8, etc.).
•
16-bit digital modules may only be assigned initial addresses whose byte number can be di-
vided by 2 (e.g. 0, 2, 4, etc.).
•
8-bit DI/DQs are addressed with the even byte address.
•
16-channel analog modules may only be assigned the initial addresses 128, 160, 192 and 224.
•
8-channel analog modules may only be assigned the initial addresses 128, 144, 160 to 240.
Example
A 16-bit digital input module is plugged into slot 2. To assign it the initial address 46.0, proceed as
follows:
•
Check whether the byte number of the desired initial address can be divided exactly by 2, since
you are dealing with a 16-channel digital module.
46 : 2 = 23 Remainder 0
•
Set the number of input channels (switch at ON).
•
Take the address switch setting from Figure 10.38 and set it on the DIP switch with slot
number 2.
1 The digital input/output module (6ES5 482-7LA11) is handled like the 16-channel modules.
