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).
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.

The driver’s S7 blocks are not protected and fully commented. No hidden code, everything is before your eyes
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.
The following example shows an entry level solution by Siemens (CP341 and its loadable driver) and an alternate solution using a cheaper CP340 and RUNMODE driver.
