Runmode, programming Siemens PLCs

Free tools, hints, tips and tricks. Interesting and specialized applications are also on sale, all developed by programmers for programmers.


xCP MODBUS SLAVE and MASTER for S7-300/-400 PLCs

CP-independent, plain Step-7 code MODBUS drivers

Runmode xCP stands for “cross Communication Processors”, a software driver that is not tightly wrapped around any specific S7 CP. It thus allows a large degree of freedom in selecting for your project the best serial Communication Processor (CP) at the lowest price.

xCP MODBUS is a set of S7 blocks coming in two versions: Modbus RTU Master and Modbus RTU Slave.


Your CP choice may include rack mounted or networked CPs, either by Siemens or by other manufactures (e.g. Vipa, Wago, Helmholz, etc).


Tunnelling Modbus RTU, go Ethernet to serial!

xCP drivers can also be used for Modbus tunnelling via Ethernet. This means that by using an Ethernet connection you can access non-Modbus/TCP serial compliant devices . If your S7 PLC is equipped with an Ethernet port, simply use an Ethernet-to-serial converter to act either as Modbus RTU Master or Slave.

No ties

The driver’s S7 blocks are not protected and fully commented.  No hidden code, everything is before your eyes


No multiple license hassles

As long as you sell your PLC programs, the license grants you to include an unlimited number of copies of the driver.  So buy once and reuse as many times you need. The only bound is the commitment to not resale nor distribute freely the driver.
