A BOUT I/O M ODULE A DDRESSING
I/O module part numbers B1204S (4-port relay), B1216S (16-port) and Z1216S use RS485
communications. A default address of 99 is assigned to these modules when they leave the
factory. Their addresses may be reassigned under program control from the replace function
under the Configure I/O Modules screen. To readdress these modules first add them (Add
function) as module address 99. Once added the module may be selected by its module number
(not address) and readdressed by doing a replace on that module number with a similar type
module assigned a different address.
NOTE – If a module assigned address 99 is already installed it will either have to be temporarily
disconnected from the RS485 string (use Disable) or readdressed using the process below before
an additional module can be installed using this process. When a module is readdressed all of its
input and output settings are retained so there is no penalty for readdressing a module currently
addressed at 99.
Add:
Add is used to create a new module. When Add is selected the screen shown in Figure 6 will be
displayed. A module type and module address are assigned by the user and submit is pressed.
The newly created module will then be displayed in the module inventory and its associated
inputs and/or outputs will be displayed on those screens. As previously discussed all newly
created modules having inputs will be created with all inputs defined as unassigned. An RS485
module should be assigned a two character hexadecimal address between 01 and FF. RS485
address 00 is reserved for Ctek's PowerMinder module. USB modules are assigned an eight
character address which is supplied with the module.

Delete:
Delete is used to remove a module from the overall configuration. When selected the Delete
screen will be displayed as shown in Figure 7. To delete a module enter the modules number and
press submit. When a module is deleted all of its input and output settings are permanently
erased.
